General Product Description The 3M Brand Organic Vapor Monitor #3500 is a sampling badge to be worn near the breathing zone of personnel exposed to potentially hazardous organic vapor environments. It is designed to measure average concentrations over a measured time interval of 8 hours or less. The monitor requires no sampling pump. It is analyzed using techniques similar to those outlined in NIOSH Physical & Chemical Analytical Method 127 for charcoal tubes. Analytical assay is correlated to environmental contaminant concentrations using data supplied by 3M Company. * The 3500 monitor is designed to be analyzed by the user or by an independent laboratory. The 3510 is the same monitor but also includes a pre paid analysis service from 3M for up to three compounds per monitor. II. Principle of the Method 1 The contaminant enters the monitor by diffusion and is adsorbed by an active adsorbent medium (charcoal) inside the badge. The amount of contaminant adsorbed is determined by exposure time and contaminant concentration present in the sampled environment. 2 A measured volume of a suitable solvent is added to the monitor to desorb the collected organic vapors. 3 A portion of the desorbing solvent, containing the organic contaminants, is withdrawn from the monitor and analyzed by gas chromatography. 4 The weight of organic contaminant, determined by G.C. analysis, is converted to time weighted average exposure; using data supplied in the 3M Compound Guide and Calculation Guide. This product information may be obtained by completing the reply card found in each instruction guide. 3M 103885 3 III. Monitoring Instructions 1. The monitor and closure cap are packaged in a resealable bag. Shipping carton can be used to mail exposed monitors to the lab for analysis. Individual 3510 monitors can be sent to 3M in pre paid mailers supplied. 3. Before removal of monitor from clear pouch, record the following on resealable bag and your data log. a) Monitor code from monitor back label b) Date of sampling c) Employee or area code d) Compounds to be analyzed for e) Temperature and relative humidity 2. The monitor itself is contained in a clear plastic pouch. DO NOT REMOVE MONITOR FROM CLEAR POUCH UNTIL READY TO START SAMPLING. 4. Remove monitor from clear pouch by tearing at notch above pouch seal. 4 3M 103886 5. Record start time on back label of the monitor. MOVE TO STEP 6 IMMEDIATELY, 8. Snap closure cap firmly onto monitor body Be sure the two port plugs are firmly seated, SAMPLING IS NOW TERMINATED. 6. Attach monitor to employee as near to the breathing zone as possible. DO NOT REMOVE WHITE FILM AND PLASTIC RING. 9. Record END TIME on back label of the monitor and on your data log. 7. After sampling period is ended, remove plastic ring and white film MOVE TO STEP 8 IMMEDIATELY. 3M 103887 5  i 30CO 10. In spaces provided, record sampler number from back of sampler, date of sampling, employee I.D., Compound(s) to be analyzed, temperature & relative humidity, if extreme. 11 . Return monitor to resealable bag with matching monitor code number. Return bags to mailers, seal and send to laboratory for analysis. KEEP MONITORS IN AN AREA FREE OF ORGANICS, IV. Preparation of Blanks 1. A blank is a control sample monitor that tells the laboratory analyst if any background contamination is present due to the handling of the monitors in the actual work environment. 2. Prepare a blank for each separate set of exposed monitors as follows. Refer to Section III, Monitoring Instructions. a) At the monitoring site, remove a monitor from the clear pouch (Sec. Ill, Step 4). b) Immediately remove the white film and plastic ring and replace with closure cap (Sec. Ill, Steps 7 & 8). c) Return monitor to its resealable bag and label bag "Blank". Record monitor code numbers for which this monitor serves as the Blank. d) Submit the blank, along with exposed monitors, to the laboratory for analysis. 3M 103888 6 V. List of Recommended Compounds for the #3500/3510 Organic Vapor Monitors A list of compounds suitable for measure ment by the monitor are found below. The complete compound guide notebook can be obtained by completing the card in each instruction booklet. For compounds not on this list, consult OH&SP Technical Service 612/733S234. Based on laboratory testing of over 70 or ganic vapors with the 3500 monitor, and based on the similar chemical nature of organic vapors and their adsorbtion on charcoal, OH&SP recommends the 3500 for use in monitoring the more than 135 or ganic vapors listed in the NIOSH/OSHA Pocket Guide to Chemical Hazards (DHEW publication No. 78-210).

Subsequent sampling may be done with the 3M 3500/3510 Monitor if determined, by #3520 results, that contaminant concentrations are within the 3500/3510 capacity limits. 3M 1Q3889 7 VIII. Calculation Procedures 1. Using gas chromatography analysis methods, determine the weight of each contaminant present on the monitor in milligrams. 2. Correct the weight by subtracting out the number of milligrams, if any, found in the blank sample for each individual contaminant. 3. Determine the recovery efficiency for each contaminant. The procedure found in the #3500 Compound Guide Notebook titled, "Recommended Procedure for Determination of Recovery Coefficients" should be utilized. To obtain this information, please send the reply card found on the back page of Instruction Booklet 4. Using the Organic Vapor Monitor #3500 Compound Guide, determine the sampling rate for each contaminant. 5. Determine the sampling time in minutes for the contaminants from the back label of the exposed monitor. .6 Calculate the contaminant concentration using the following equations: mg (W) (10s cm'/m1) m3 " (r) (KJ (t) Where: W = Corrected weight in milligrams r = Recovery (Desorption) efficiency Kj = Monitor Sampling rate, cm3/mm. t = Sampling time, minutes 7. To calculate concentration in ppm at reference conditions of 298K and 760 mm.Hg. use the following equation; ppm = mg 24.45 m3 x MW Where; MW = Molecular weight, g./mole The above equations calculate concentrations that can be strictly compared to OSHA standards only if the temperature during sampling was 298K (25C or 77"F). If sampling temperature is significantly different than 298K, then a correction can be applied as follows: Temperature corrected concentration C,, C0 = mg /298K|/i HP x\ Ts I C0 = ppm A|298Kjy; Where: Ts = Temperature at Sample Site in K. This correction eliminates an error of approximately 1 % for every 10F (5.6C) increment above or below 77F (25C). See the 3M Brand Organic Vapor Monitor #3500 Calculation Guide for complete details and example. calculations. 8. #3500 CALCULATION GUIDE The #3500 Calculation Guide is designed for the customer involved in the analysis of the #3500 by the gas chromatograph. The #3500 Calculation Guide describes in detail the steps involved in calculating parts per million (ppm) or milligrams per cubic meter (mg/m3), when analysis and result tabulation are performed by the customer. The Guide also includes a discussion on diffusion theory and a derivation of the equations in the calculation procedures. The #3500 CALCULATION GUIDE is part of Section Three of the #3500 COMPOUND GUIDE NOTEBOOK -LABORATORY PROCEDURES. Notice: 3M disclaims responsibility for any comparison of test data to any existing or future health and safety standard regulating exposures to organic vapor as to whether such standards are or are not adequate to insure the safety of persons or property. 3M warrants only the accuracy of the sampling/ analytical methods and the data obtained thereby. 10 3H 103892 IX.
