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. Jie 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. 3M also provides a complete analytical service for the #3500. The 3M laboratory specializes in this analysis. 3M analysis mailers are enclosed in every box of monitors. 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to desorb the collected organic vapors. 3 A portion of the desorbing solvent, containing the organic contaminants, is withdrawn from the monitor and analyzed by gas chromatography. 4 The weight of organic contaminant, determined by G.C. analysis, is converted to time weighted average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 103200 3 III. Monitoring Instructions 1.

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 3. Let monitor stand for '/a 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 103206 9 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) 10* cm'/m1) m3 " (r)(fg(t) Where: W = Corrected weight in milligrams r = Recovery (Desorption) efficiency K, = Monitor Sampling rate, cmVmin. 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 298"K (25"C or 77"F). If sampling temperature is significantly different than 298K, then a correction can be applied as follows: Temperature corrected concentration C, C,, = mg (298K',/z m3 x\ Ts ) C,, = ppm ^298iC|/a Where: Ts = Temperature at Sample Site in K. This correction eliminates an error of approximately 1% for every 10"F (5.6"C) increment above or below 77"F (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 103207 10 o IX.
