3M Brand Organic Vapor Monitors #3500/3510
I. 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.
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containing the organic contaminants, is withdrawn from the monitor and analyzed by gas chromatography.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.

III. Monitoring Instructions
I. 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 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.

5. Record start time on back label of the
monitor. MOVE TO STEP 6 IMMEDIATELY
O- 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

1U. 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 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.

VII. General Analysis Procedure for #3500
For detailed instructions for analysis including recovery coefficient determinations, please return enclosed card in section IX A complete #3500 Compound Guide Notebook will be promptly sent for your information.
1. Samples should be inspected in the following areas: a) Monitor code matches code recorded on bag. b) Closure cap is firmly snapped to monitor body. c) Closure cap plugs are firmly seated in the cap ports.
4. Open both ports. Insert decanting
spout into the rim port and carefully transfer the liquid to a sampler vial used with the automatic sampler of the gas chromatograph. The vial is immediately sealed. An alternate procedure is to use a syringe to withdraw a sample from the center port for manual injection into the gas chromatograph.
2. The center port is opened and 1.5
milliliters of carbon disulfide or other suitable desorption solvent, is injected. The rim port can be open to allow venting. Reseal both ports.
3. Let monitor stand for Vi hour with
occasional gentle agitation applied.
5. Gas chromatographic analysis is
conducted as outlined in NIOSH
P&CAM 127. The corrected weight for each contaminant, collected by the monitor, is obtained by subtracting out the contribution of the blank sample.
3M 104011

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 cmYm3) m3 " (r) (Ko) (t)
Where:
W = Corrected weight in milligrams r = Recovery (Desorption) efficiency K,, = Monitor Sampling rate, cm3/min. t = Sampling time, minutes
7. To calculate concentration in ppm at
reference conditions of 298I,K and 760 mm.Hg. use the following equation:
ppm = mg 24.45 m3 * 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 C0
= mg /298Kf m3 \ Ts )
C,, = ppm x|2^K|'/2
Where: Ts = Temperature at Sample Site In K.
This correction eliminates an error of approximately 1% for every 10F (5.6"C) 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 the 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.
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.
