VINYL CHLORIDE LEAK DETECTION AND ELIMINATION PROGRAM Monitoring Equipment Calibration and Maintenance Monitoring Program Plan of Action Definition of a Leak SL 090993 1 I. MONITORING EQUIPMENT A. Fixed Point System One ten-point Model 505 Areas process chromatograph plus a paper tape printer, which continuously prints analysis results as they are completed. This system is also tied to a central computer which provides shift and daily reports containing plant and point time-weighted averages, a listing of analyses above a pre determined level, and the time thereof for each point. An audible alarm indicates when the predetermined level has been exceeded. There are eight points monitored in the process area; each point is sampled every 90 seconds (approximately). A detailed description of the Areas equipment is provided in Attachments I and II. B. Semi-Portable System Two HNU Model PI 201 trace gas analyzers, the specifications of which are described in Attachment III. The principle of operation is the same described in Attachment I for the HNU Model PI 101 portable detector. Accessories Include an audible alarm and the dual set point option. One such system is presently installed; we plan to purchase a second unit. C, Portable Detectors One Model 90 Century organic vapor analyzer and one Model PI 101 HNU Systems analyzer are presently used in the plant for leak detection. Both of these instruments, or upgraded models, will be employed in the formal leak detection program. A description and specifications for these instruments can be found in Attachments IV, V, VI and VII. SL 090994 CALIBRATION AND MAINTENANCE A. Areas System The vinyl chloride monitoring system is calibrated and span checked on a daily basis, Monday through Friday exclusive of holidays, Saturdays and Sundays, with a gas mixture containing 5 ppm vinyl chloride. A calibration gas cylinder, the gas analysis of which is traceable to the National Bureau of Standards, or an equivalent gas mixture, will be used. Maintenance will be performed on an asneeded basis based upon a daily check of the operation and condition of the system. B. Semi-Portable System The HNU Model PI 201 analyzers will be calibrated once monthly with a gas mixture containing 5 ppm vinyl chloride. A calibration gas cylinder, the analysis of which is traceable to the National Bureau of Standards, or an equivalent gas mixture, will be used. Maintenance will be performed on an as-needed basis, depending upon the operation and condition of the equipment. C. Portable Meters The portable hydrocarbon detectors will be checked monthly to verify that they have not lost their sensitivity to vinyl chloride. The gas used for this test will come from a gas cylinder containing 5 ppm VCM, the gas analysis of which will be traceable to the National Bureau of Standards, or from an equivalent gas mixture. Maintenance will be performed on an as-needed basis based upon the operation and condition of the detectors. SL 090995 111. MONITORING PROGRAM A, VCM Formation and Purification Area 1. Eight of the 10 Areas system points are located in the VCM formation and purification area as shown on the attached plot plan Dwg, No. 65A-2100.4. There is also one point located in the plant laboratory and one point is used for calibration. The location of the points relative to equipment in vinyl chloride service (shaded areas) can be seen in the plot plan drawing. Samples are obtained from nine of the 10 points on a continuous sequential basis. Cycle time per point is approximately 90 seconds. The entire formation and purifi cation area is covered every 13 and one-half minutes. The chromatograph is located at the control room. 2. In addition to the fixed point system, the portable hydrocarbon detector will be used routinely on a weekly basis to check for small leaks from equipment in vinyl chloride service. A schedule and checklist will be developed which insures that all sections of the VCM formation and purification area are checked at least once per week. The items to be checked during this routine equipment check include control valve and block valve packing glands, flanges, pressure gauges, impulse lines and connections, sample points, and pump seals, B, Shipping and Storage Areas These areas (see list below) are physically separate and in some cases remote from the vinyl chloride formation and purification area. Due to the long distances which would be involved, these areas do not lend themselves to use of the same type fixed-point monitoring system used in the VCM formation and purification area. For that reason, a leak defection program has been developed utilizing the portable and semi-portable detectors and area ambient air samplers. It should be noted that there are fewer potential sources of leakage In these areas as compared to the vinyl chloride formation and purification area, and, furthermore, the equipment in these areas is not in con tinuous operation, further reducing the potential for leakage. Also, the equipment In these areas is relatively safe from internal or external corrosion since the material handled is product-grade VCM which has been dried and filtered and since these facilities are located away from the process area. In addition to the routine visual inspections conducted in these areas several times each day by Operating personnel, the following program is proposed: 1. Day Tank Storage (See Dwg. No. 65A-1100). This area will be canvassed twice per week nm* th the portable hydrocarbon detector. This routine check will include control valve and block valve packing glands, flanges, pressure gauges, impulse lines and connections, sample points and pump seals. f SL 090996 2. Sphere Storage (See Dwg. No. 65A-1100). Two spheres are located as shown on this drawing. A third is located at the barge and ship loading dock remote From the area shown. These areas will be canvassed twice per week with the portable hydrocarbon detector. This routine check will Include control valve and block valve packing glands, flanges, pressure gauges, impulse lines and connections, sample points and pump seals. 3. Tank Car Loading (See Dwg. No. 65A-11Q0.) One semi-portable HNU analyzer will be located at the loading rack and will be operated continuously during loading operations. In addition, the portable hydrocarbon detector will be used routinely to survey the area once per week. This routine check will include block valve packing glands, flanges, pressure gauges. Impulse lines and connections, and sample points. 4. Barge and Ship Loading. One semi-portable HNU analyzer is located at the dock and is operated continuously during loading operations in compliance with Coast Guard regulations. f SL 090997 IV. PLAN OF ACTION All indications of possible leakage by the monitoring equipment will be reported to the supervisor in charge. The supervisor will evaluate the leak detection information considering atmosphere conditions such as wind velocity, wind direction, and relative stability; current operations being undertaken such as opening equipment after the requirements for opening have been met in accordance with the regulations; and current operations being carried out in other portions of the complex that would tend to increase ambient concentrations temporarily. The proper action to be taken will be determined by the supervisor. A suspected leak will be searched for using the portable hydrocarbon detec or until the leak has been found, has subsided or fhe problem has been otherwise identified. Personnel performing the leak search will wear appropriate protective equipment. Any collective action necessary will be commenced immediately and will include but not be limited to: A. Isolating the source of the leak so that the leakage is stopped and the source repaired, replaced, or acted upon according fo standard operating procedures as soon as it is feasible to do so. B. Repairing the equipment or acting upon the equipment in line by tightening, closing, etc., so that the leak is stopped. C. When necessary, curtailing operations until repairs can be made. D. Checking the source again after the leak has been corrected to insure' that the leak has not reoccurred. Anon-going program of prevention of leakage and elimination of troublesome leakage problems will consist of: A. Implementing procedures for installation and operation of equipment so that possible leak sources will be eliminated (i.e., pressure testing equipment prior to its being put into service or making sure hoses, sample bombs, etc. are connected properly and securely). B. Checking known troublesome leak sources more frequently until the problem is resolved, C. Modifying the routine leak patrol schedule if such is indicated by experience in Order to insure maximum effectiveness of this program. SL 090998 V. DEFINITION OF A LEAK The following guidelines are proposed as to when action to locate and eliminate a possible leak should be taken. These guidelines will be reviewed periodically and modified as needed in order to insure the continuing improvement of the leak detection and elimination program. A, Areas Fixed-Point System Normal background concentration levels range between 0,1 and 4.5 ppm, averaging about 0.5 ppm. Representative data from the Areas monitoring system are appended as Attachments VIII and IX. A VCM leak will be considered as indicated by two successive readings on the Areas monitor of 5 ppm or above. B. Semi-Portable Detectors A VCM leak will be considered as indicated by any reading in excess of 1 ppm. SL 090999 Attachment I ARCAS DIVISION OF ANACON INC.

The Anacon/Arcas gas chromatograph is an advanced instrument comprising several unique features and devices not available with ordinary gas chromatograph equipment. In principle, the Model 505 meters a small quantity of sample and then measures the individual gaseous components which are separated by a process of selective retention and elution. This separating process takes place in a tube filled with special packing materials. The various components adhere to and leave the packing medium at a rate proportional to their relative affinity for these materials. The differences in affinities provide the means for separating--and thereby identifying--individual gas components. The quantity of the component is determined by the magnitude of the detector signal. The model 505 is now being used world-wide for applications in chlorine production, natural gas plants, refineries and many other operating units of the chemical and petrochemical industries. Typical applications include the determination of hydrocarbons in stack gas, pollution monitoring and control, material balance calculations, vinyl or methyl chloride in air, product purity, butanes to storage, demethanizer bottoms, overheads, and so on. The model 505 offers a field-proven and practical answer wherever quantitative chemical analyses are required for safer and more profitable operation. SL 091001 i i i* i a ! 3 The Model 505 Gas Chromatograph offers a new dimension in efficiency, operational reliability and serviceability. Moreover, the analyzer and program control equipment offer a high degree of application versatility because they may be used directly in a variety of analysis systems. Three of Ihe more popular systems are illustrated below. 1 STRIP CHART RECORDING This system incorporates a millivolt strip chart recorder and presents data as a chromatogram (spectrum), gate check, or bargraph. it is probably the most commonly used whenever lowest cost and minimum complexity are of importance TREND RECORDING The addition o( plug-in peak pickers or integrators and memory units to the Programmer permits easy interfacing to voltage or current trend recorders An I/P transducer also makes the system compatible with standard pneumatic recorder/controliers. COMPUTER PRINTOUT A standard Computer Interface Assembly substitutes for the normally used Programmer when the analyzer is to be controlled by a computer. Since the Model 505 operates entirely by 5 VDC commands, computer compatibility is already built-in. Analyzer Fig. 1 Prog rammer Recorder Data Presentation Analyzer Fig. 2 Programmer Fig. 3 3 COM PU Tf t FfffNTOt/T Data Pratenfation SL 091002 THE ANALYZER The Model 505 analyzer embodies the latest developments in the gas chromatographic field with respect to sensitivity, gas flow and electrical components and, especially, ease of maintenance. It contains all of the components necessary to perform the chromatographic measurement. The design exemplifies simplicity and operational reliability. It provides for complete and open access to all components which require periodic preventive maintenance. It is equipped with the famous Areas sample and switching valve that can be field stripped, cleaned and reassembled in less than ten minutes. AC is isolated from DC--a feature which contributes to the low signal-to-noise ratio so vital in computerized and modern high sensitivity applications. Even the AC solenoid valves are operated through relays actuated by 5 VDC command signals from the programmer or computer. Condulets are explosion-proof, suitable for Class I, Group C or D, Division 1 areas. The unit employs the fast acting circulating air bath concept. Oven air is distributed rapidly with a. fresh air flow of one CFM; heat-up from room temperature to operational 220F requires one hour, A proportional, zero-firing, solid-state controller maintains the proper temperature. Analyzer components are usually mounted on a sub-panel which allows a selection of mounting methods. This sub-panel may be wall mounted directly, or, with legs attached, may be floor mounted. The very same sub-panel may also be installed within a weatherproof fiberglass housing. The analyzer is ready for immediate book-up with the 505 Programmer or Computer Interface Assembly. J PRINCIPLE OF OPERATION The Model 505 System comprises several unique features and advanced devices not available with ordinary gas chromatography equipment. But the heart of the unit is its separation column, for it is this device which performs the separation of the gas components. The separation column consists of a length of lubing that is filled with a highly porous or high-surface-to-volume packing material that has been coated with a heat stable liquid. Finely sieved sand, crushed firebrick or other similar microporous materials are used. Alternatively, microporous resins and molecular sieves can also be used without the liquid coating. A sample to be measured is removed from the main process line and in troduced into the gas chromatograph sample stream. After passing through a sample conditioning system, the sample flows through a special "sampling loop". The purpose of the sampling loop is to always assure a uniform sample size. When a sample is to be analyzed, a valve action releases the measured volume from the sample loop where it is flushed into the separation column by a carrier gas stream. In a typical separation column, the gas sample is absorbed into the liquid coating and becomes a component of this liquid. The rate and/or degree at which the gas sample is absorbed is dependent upon the affinity each of the gas sample elements have with respect to the liquid solution. And therein lies an initial separation effect. After the component fluid has been fully absorbed it begins to desorb. Since chemicals have different desorption characteristics, each component is effectively separated. The relative times at which the separated (desorbed) gas substances leave the separation column ultimately determines their identity.

Some models will even handle the most corrosive samples with minimum maintenance. Field disassembly for cleaning Is accomplished simply by loosening a single center-mounted tension screw and lilting off the valve parts. Valves can be supplied In stainless steel, Kol-F, Hastelloy and other materials as determined by the chemicals to be processed. rs SL 091004 5 About Chromatographic Detectors 0 Once the separation column has performed its function, the detector senses the passage of components and converts their presence into electrical signals. These signals describe a precise electrical analog of the concentration of components which are compared with a known standard of the gas substances. There are various detection techniques but the Model 505 usually uses either a Thermal Conductivity (TC) or a Flame Ionization Detector (FID). FIG. 5 TC DETECTOR FIG. 6 FI DETECTOR c THERMAL CONDUCTIVITY DETECTION The Thermal Conductivity Detector (TC) is essentially a Wheatstone bridge which is able to determine the specific gas substance by measuring the degree to which heat-conducting properties ol the column effluent change as compared with a known reference. The TC detector circuit (see Figure 5) consists ot a pair of heated resistance filaments mounted inside separated cavities. One cavity or cell receives the sample and carrier while the other receives only the earner (reference) gas If the separated gas component entering the cell has different heatconducting properties than the carrier, the heated filament will cool or heat... causing a relative imbalance in the bridge The extent of the imbalance, which is observed as a voltage output change, is related to the concentration of the separated component. Typically, the generated signal is fed to a strip chart recorder. The standard TC unit is supplied in a fast flow through configuration although an optional dual carrier version is very popular for some applications. The latter permits separate carrier gas flows into each filament leg for analyzing hydrogen and other components in recycle streams and synthetic natural gas processes. A variation of the standard TC unit is the Diffusion Detector. This unit is constructed so that the sample component does not come in contact with the filaments. This detector is usually required for corrosive samples such as chlorine or hydrogen chloride. FLAME IONIZATION DETECTION An FID is usually recommended where a high degree of sensitivity is required for the measurement ol very small quantities of organic materials. The detector consists of a small gas burner producing a hydrogen-oxygen flame, an ion collector, a polarizing voltage source, and an electrometer amplifier (see Figure 6) Since the combustion of hydrogen produces only a few ions by comparison with an equal amount of hydrocarbon, it is relatively easy to distinguish the two. The sample hydrocarbons which ionize in the flame, generate a response in proportion to the percent weight of carbon. The FID is insensitive to inoi games and is not otlected by moisture or moderate changes in temperature or pressure. 091005 SIMPLIFIED EXPLANATION OF THE SAMPLING PROCEDURE PROCESS LINE 1 Sample to be measured is removed from process line and flows into sample stream. "~C <llfl n Gas sample stream is filtered to remove any extraneous solid particles such as rust, carbon or other materials which could damage or plug instrument components. hil o xO A pressure regulating device maintains constant pressure so that the sample line is unaffected by momentary surges or main source pressure changes. "v A two-way block valve (on-off) blocks the sample flow and allows the sample loop pressure to equilibrate to atmospheric pressure. *"5 A flowmeter shows the sample rate flowing in the sample stream by visual indication. The amount of flow is easily adjusted by a needle valve on the flowmeter G The sample stream flows through the sample loop until such time as the sample is analyzed, (see Principle of Operation) flowmeter MODEL 505 ARCAS J 1 FLOW RESTRICTION 7 A slider type switching valve effects the sampling process. When closed, the sample gas "trapped" in the sample loop is flushed out and earned into the separation column by the earner gas where each gas component is separated. THREE-WAY c3 BLOCK VALVE 3 A detector senses the passage of components and converts their presence into electrical signals. These signals describe a precise electrical analog of the quantity of the gas component which is compared with a known standard of the gas components. Q The sample gas passes through a three-way block valve and is either (1) vented into the atmosphere or (2) returned to the main process line. VENT 7 RETURNTO PROCESS LINE SL 091006 ABOUT CHROMATOGRAPHIC CONTROL The chromatographic control unit programs the timing and sequencing of the actual sampling process. The programmer unit can be used with either the cam timer or the new solid state digital timer. Cam timing is suitable for applications in which slow, less critical timing for the analysis is adequate. Digital timing is recommended for applications involving frequently varied chromatographic measurements, high precision and for both long and high speed analyses. CAM TIMING The standard cam timer offers simplicity, low cost, complete accessability to all cam adjustments and electrical connections. It is coupled to an indicating sequence position control on the front panel. The cams must be individually reset, for each new application or timing sequence. View at top right shows a programmer with an FID detector controlled by cam timing. DIGITAL TIMING The all solid state digital timer provides a permanent memory for each timed function by means of three self-indicating push button switches. The memory function is unaffected by power failure or by turning off the instrument. The timer has up to 13 channels; nine with adjustable start and adjustable stop times. Each function such as sample inject, column switch, auto zero, and attenuator switching has its own channel with the time displayed in three digits. Any one of the function's start or stop times can be changed without changing any other part of the timing program, and the change can be made while the programmer is in operation. Function cards are plug-in Each card is keyed separately Component markings remain visible Solid-state throughout No AC power exists beyond the transformers, motor and rectifiers Complete accessibility to all parts 9 SL 091007 Sampling System Components The selection of the right sampling system components is as important as the process chromatograph itself. Anacon/Arcas. as a single-source supplier, can provide all of the necessary components including sample probes, filters, regulators, flowmeters, vaporizers, etc. SAMPLE PROBE WITH riifnpp VAI VFS ______ The sample probe permits removal of a truly valid sample from the faster flowing turbulent middle section of a process line. The probe tip prevents blowout by line pressure and can act as a prefilter by special orientation. The probe may be installed and removed while the process line is under pressure. No line shutdowns. FRESH FLOW Fll TFR ........ . _ This device is designed to remove any extraneous solid particles such as rust, carbon or other materials which could damage or plug instrument components. This filter is self-cleaning and acts as a dropout pot and de-mister as well. GAS RFftlll ATHR Especially designed for corrosive service, this gas regulator can handle wet or dry chlorine, hydrogen chloride and other gases. Materials of construction which contact the chemicals are Kel-F or Teflon. The regulator maintains constant pressure so that the sample line is unaffected by momentary surges or main source pressure changes. > r' *; .' -*n 1 `' i ii SL 091008 BLOCK VALVES These two-way and three-way block valves are constructed of Teflon for corrosive service and are operated by compressed air through piston operators. The special seat design assures long, trouble-free service. Specify either the two-way or three-way version. FLOWMETER ______________________ The Anacon/Arcas flowmeter is constructed especially for use in corrosive service such as hot, wet chlorine. Other applications include corrosive gases or liquids from hydrogen chloride, perchloro-ethylene or other service where Teflon and glass sample wetted components are required. Anacon/Arcas usually recommends various commercial grades for ordinary chromatography applications. However, almost 40 special high performance versions are available. Write for Bulletin 150. Accessories and Options COMPUTER INTERFACE A computer can replace the programmer and be connected to the analyzer through a Computer In terface Assembly which contains DC power supplies, current meter and switches for manual operation of the analyzer. This method permits more flexibility of analysis and data handling. Various detector response factors can be programmed into the computer; peak areas can be calculated digitally and the total analysis normalized. OPTIONAL ANALYZERS The Model 505 Process Chromatograph described in this brochure uses a relatively small oven. For special applications, Areas offers two additional optional models. One, a larger air-bath oven, is used when additional space is required for complex analyses utilizing several switching valves, columns and possibly dual detector channels. A second, a heat-sink oven, is used in cases where no reliable source of instrument air is available in the area of installation. This latter model contains an aluminum heat sink in an explosionproof condulet housing.

Only then can t personnel be alerted to their presence -- enabling them to take corrective action. Anacon pollution monitors (ARCAS) are safe, accurate and reliable. IN ATMOSPHERE The ARCAS VCM analyzer takes a sample of the atmosphere, separates it into its discrete components, identifies, quantifies and then re cords, alarms, shuts down, or performs other functions to help maintain safe conditions. The VCM analyzer suffers no interferences from water vapor, methane, COi, vinyl acetate and most other gases likely to be found in atmospheric samples. It normally analyzes with in a 1 minute time cycle. It can be calibrated down to a remarkable interference-free 1 ppm VC full scale. It is also compatible with computer/data-loggers for complex multi-stream applications which are also supplied by ARCAS. IN WASTEWATER A specifically programmed ARCAS Model 705 analyzer can measure vinyl chloride in water samples down to a detectability limit of 2 parts per billion. A new technique* permits the partitioning (and concentration) of chlorinated organics and hydrocarbons from wastewater, seawater, or drinking water sample streams. Those concentrated gaseous components are then easily separated identified, quantified, and documented in ways similar to that employed by the VCM atmosphere analyzer. Sampling is very simple. A nominal water flow rate of 500 cc/min from a constant head source is all that is needed; the ARCAS analyzer does the rest. There are no problems associated with particulates, salt build-up, flame blow-outs, or low sensitivity found with other techniques. Other functions for providing records, alarming, shutting down, etc., are also available. ARCAS vinyl chloride pollution monitors, whether for atmospheric or water samples, are based upon the well-proven series 505 Process Gas Chromatographs. Because ARCAS tech nology permits such rapid vinyl chloride analy ses, multistream applications are encouraged. For example, a 15:stream air monitor with a one minute analysis time, will check each sampling position once every 15 minutes; but any reason able number of streams may be sampled. The cost savings in using a single instrument to cover so many sampling points with a specific, sensi tive and accurate analysis is considerable. The VCM is also readily programmed to measure organics other than vinyl chloride. `Licensed from Dow Chemical Co.

The instrument uses the princiole of photoicnizaticn as the analytical technique and overcomes many of the problems inherent in current trace gas analysis in strumentation. These problems presently include poor limits of detection slow and sluggish time response, background elec tronic noise or drift and a lengthy series of precise technical operations necessary to properly use the instrumentation. In addi tion, many of today's portable analyzers remain heavy, cumbersome instruments that require additional portable equipment such as sample pumps or compressed fuel and zero gases or bulky power packs for operation. The advanced technology employed in the photo-ionizer successfully overcornea these disadvantages. For example, the limit of detection for most species is extended down to 0.1 ppm --an increase of 10-100 fold over many conventional in struments--while still maintaining a wide dynamic operating range (0.1 to 2000 ppm). This improved sensitivity allows industrial hygienists to make measurements at or below the TLV's (threshold limit values) established by OSHA. Time response is greatly improved by several design advances. The location of the sensing chamber at the sampling point in the hand-neld probe, the fabrica tion of al I sample contact areas with inert fluorocarbon materials and a rapid sample flow through a small analyzing chamber eliminates sample hang up (adsorption) and minimizes sample transit time in the instrument. The problems of delayed time response and instrument sluggishness are eliminated. Total time response to 90% of a full scale concentration change (0-2000 ppm) is less than five seconds-a signifi cant feature when the instrument is used to locate plant "hot spots" or to detect leaks. All solid state electronics and state-ofthe-art circu't design have virtually elimi nated conventional instrument drift and background noise. Zero drift is less than 1% over 10 hours. The excellent stability and drift free electronics allow accurate measurements, even at very low concentra tions. The Model P1101 is one of the simplest analytical instruments to use since it has only three operating controls and unskilled personnel are easily and quickly trained to operate it. An easy to read 4'/2" linear scale provides a readout directly in units of con centration (ppm). Other feature's include an electronic zero that eliminates the use of a zero gas, and instrument calibrations that hold for weeks. The elimination of a flame, igniters and compressed hydrogen fuel make the photo-ionizer simplerto use than a flame ionization analyzer while providing an unusually safe instrument. This lightweight (less than nine pounds) instmment was designed pri marily as a portable analyzer for survey work and leak detection. However, the unit can also be set up as a continuous station ary monitor powered by 110V through its battery recharger/converter system. A strip chart recorder can be attached to the out puts (0-100 mv) provided. Further detai fs about the principle of operation and the significant technical advances this instrument provides are described in the following pages.

Return the postcard for details on your application. rapid response Response to changes in con centration is extremely rapid. A 90% of full scale change (0-2000 ppm) takes less than five seconds. In addition, the sensor is located at the sampling point rather than inside the instrument. This eliminates the problems of hydrocarbon adsorption and transit time through a sampling tube, all of which can delay the real time response by 30-45 seconds or more. .e 1 a AC/DC operation-The instrument power is sup plied from a 12 VDC rechargeable battery which gives a minimum of 10 operating hours before recharging is necessary. The AC recharger pro vides the option of operating the unit continuously from 110V AC so that the instrument can be used either as a portable unit for industrial hygiene sur veys and leak detection work or as a continuous stationary monitor. portability The instrument is truly portable, with a total weight of less than 9 pounds (4.1 Kg) com plete. No additional bulky power packs, sample pumps or cylinders of fuel gas or zero gas are needed. When not in use, the hand-held sensor is stored in the instrument cover and the total package measures 21 cm wide x 13 cm deep x 24 cm high.

The MEASUREMENT position allows the choice of a 0-2 ppm, 0-20 ppm, 0-200 ppm or 0-2000 ppm full scale range. The STANDBY mode reduces power consumption between measurements. The BATTERY CHECK al lows a manual power check before use while an LED (red indicator light) adjacent to the function switch provides an auto matic battery check indicator during operation. Zero Adjust The zero control allows electronic calibration of the instrument at the zero concentra tion point without requiring the use of a zero gas. Span To calibrate the instrument for a particular gas, this control is adjusted to the gain setting which will match the value of a calibration gas to that same read- ing on the instrument scale. This y\ v control also provides the 10 fold increase in gain that allows the 0-2 ppm full scale range. recorder outputs A signal output of O-IOOmv full scale is provided on the front panel for the attachment of a strip chart re corder. electronic zero Zero calibration is done com pletely electronically. The instrument is switched to the STANDBY mode where the UV light source is turned off but the other electronics remain on. The zero control is adjusted until the meter indi cation is zero. No zero gas or regulators are needed; no further adjustments are required. Verification tests for this technique against hydrocarbon-free zero gas show perfect agreement, safety The photo-ionizer is extremely safe to use, requiring no flames, igniters, or hydrogen fuel.

Hood ventilation rates can also be measured accurately because of the sensitivity and wide operating range of the unit, leak detection is facilitated by the rapid instrument response and extreme sensitivity. This enables the user to locate even small leaks very rapidly. residual solvent vapors such as trichloroethylene in decaffeinated coffee or degreasing operations, hexane from soybean extraction and other vapors from food, chemical processing, paint spraying or coating can bs easily and rapidly measured. Determination of the hydrocarbon removal efficiency of a scrubber or incineration process for compliance with Environmental Protection Agency (ERA), state or local air pollution regulations can be obtained. non methane hydrocarbons in the atmosphere can be measured directly since the photo ionizer does not respond to methane. vinyl chln'ide measurements in monomer plants can be made without interference from major starting materials or by-products such as ethylene and ethylene dichloride (dichloroethane). Low level vinyl chloride measurements in PVC fabrica tion processes do not have the 1-2 ppm methane background interference seen in other portable instruments. i ) s hydrogen sulfide measurements can be made rapidly and selectively through the use of a new special dry scrubbing system, which adapts to the instrument. // TV if For additional information on specific applications please fill out the attached postage paid reply card. n. .: _ ; HNU Systems, Inc. 30 Osiip:e Road Newton Upper Falls, Massachusetts 02164 Tel. 617-964-6590 0;J. t IpTj'irt. ;,,-snv* irtg \ -K v-v SL 091020 SL 091021 I i .Ol N C rm;_~y Organic Vapor Analyzes "OVA S' are higVy sensitive ---.-un-oms aliasing detection and analysis of trace quannres of organic I cpcrs .n air, Tora!ly portable, yer f ;vi 'a the capability to measure cpncennarions to less than 0,5 ?P\\, : e Century OVA has found wice acceptance in manufacturing, V em cal, and ether industries, ! gencies such a: OSKA and NiOiH use them, Insurance people and c'scn 'nvesneato-s find OVA's icealiy ;sited to their needs.

I PRINCIPLE OF OPERATION Flame ionization detectors are a precise means to detect organic vapors such as benzene, methane, styrene and vinyl chloride. A small hydrogen flame is burned in a chamber and the sample being measured is circulated in close proximity to rhe flame. Carbon-containing ions are formed whenever traces of organics are present in rhe sample. These ions are forced ro migrate ro an electrode by an electrical field in rhe derecror chamber. This results in a smell currenr which is amplified, conditioned and rhen displayed on a hand-held merer or on a strip chart recorder. The characteristics of flame ionization ollow organics ro be measured without interference in rhe presence of worer vopor, NOx. carbon monoxide, carbon dioxide and orher in-organics. %______ ;I i j i SL 091022 I The OVA-88 ond OVA-138 ore designed primarily for rhe narural gas industry, to be used os o leak derecror.

Now, with the optional GC capability, it is possible to make "on-the-spot" identification of individual compounds and to determine their concentration. luick-exchange olumns permit indiidual qualitative idenfication of a large cricty of comlounds based on heir "known reten- "me". In most ___ .Jal process es, however, a limit ed number of toxic impounds are oroduced and can be identified with one or two columns. See Illustration A (reverse side) for a typical chromatogram of a two-component mixture. Quantitative data is obtained either by comparison to reference chromato grams 'or more ac curately by "peak height anaiyais" us ing pre-established calibration charts as shown in Illustration B on the reverse side. With experience, the operator of the instrument will become very pro ficient in identify ing the peaks of critical compounds and determining their concentra tions (ppm). After detecting a concentration of total hydrocarbons above TLV of potential ly toxic vapors, a sample mav be injected into the GC System by pressing the GC Sampl ing Valve. Component vapors will elute singly from the column, after their individual retention times, into the flame ionization detector for subequent display on the hand-held meter and the strip chart recorder. The strip chart recorder chromatogramcan be interpreted "on-the-spot" by a trained operator to determine which components were in the mixture, and their concentration levels.
