C St. Paul, Minnesota 55144 3M 002252 Kr Use of the Sampling Guide Tables: The following table summarizes OSHA standards, 3M monitor sampling information and recommended sampling procedures for a variety of organic compounds for which the 3M Organic Vapor Monitors can be used to acccurately determine the environmental exposures. The table is not exhaustive and will be updated periodically. To obtain periodic updates, return the registration card contained in every box of monitors to 3M Company. A. OSHA Standards The OSHA TWA-PEL's (Time Weighted Average) given as workshift time weighted averages are taken from the Federal Register as found in 29 CRF 1910.1000 as of 1 January 1977 and are summarized in the "NIOSH/OSHA Pocket Guide to Chemical Hazards." Also included in parentheses are the current ACGIH (American Conference of Governmental Industrial Hygienist) values in cases where they differ from OSHA TWA's. These values are subject to change and appropriate publications should be consulted for the most current information. B. Monitor Samples Information * Sampling Rate All sampling rates have an accuracy of 5%. The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlines in a publication on Sampling Rate Validation. The sampling rates are tabulated as cubic centimeters/minute and micrograms/ppm-hour. The publication on Sampling Rate Validation Protocol can be obtained upon request from 3M Company. The top section of the #3520 (containing the primary absorbent) has the same geometric dimension as the 3M Organic Vapor Monitor #3500. Therefore, the sampling rates are the same, and also have an accuracy of 5%. * Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity values are tabulated in Section II - Analysis Guide, and are used to determine the length of a recommended sampling period. Because of the backup section, the effective sampling capacity of the Organic Vapor Monitor #3520 is four times greater than the values listed for the Organic Vapor Monitor #3500/3510. When sampling environments containing contaminant mixtures on environments with high relative humidity, it is difficult to accurately define the diffusions! sampling capacity. Therefore, under these conditions, the weight (Ws) collected by the secondary absorbent of the backup section can be compared with the weight (Wp) collected by the primary absorbent to determine sample validity. The ration Ws/Wp must be equal to or less than 0.50. C. Length of Sampling Period 1. General 3500/3510 When sampling for organic contaminants, full workshift sampling periods are recommended as the most comprehensive measures of worker exposure. When sampling some organic contaminants, sampling periods shorter than a full workshift are required in order to sample within the recommended capacity of the monitor. Under these circumstances, sequential sampling with several monitors can be performed. 3520 For those compounds where the recommended length of the sampling period for the Organic Vapor Monitor 3500/3510 is less than a full workshift, the length of the sampling period can be increased by a factor of four when using the Organic Vapor Monitor #3520. Because of the increased effective capacity of the Organic Vapor Monitor #3520, sampling periods longer than a full workshift are possible. The preferred recommendation is for full workshift sampling periods. 1 3H 002253 2. Effect on Humidity Recommended sampling periods have been tabulated for concentration ranges from .1 to .5 times the PEL and from .5 to 3 times the PEL for relative humidities less than or greater than 70%. These recommended sampling periods should not be exceeded when using OVM #3500/3510. 3. 'Minimum Sampling Time To confirm quantitatively the presence and concentration of a contaminant in the atmosphere, most analysts must have a minimum of 10 micrograms for G.C. analysis. A sampling period of at least 15 minutes is recommended even when 10 micrograms of the contaminant could be collected In a shorter period. For a contaminant at a low concentration level, the sampling rate of micrograms/ppm-hr. should be used to verify a sampling period during which at least 10 micrograms of the contaminant would be collected. D. Short Term Exposure Limit (STEL) The ACGIH has recommended a short-term exposure limit (STEL) as a maximum concentration to which workers can be exposed for a period up to 15 minutes continuously. No more than four (4) such excursions per day are permitted, with at least 60 minutes between exposure periods, provided that the recommended ACGIH daily TLV-TWA also is not exceeded. The STEL values summarized in the following tables can be found in the "Threshold Limit Values for Chemical Substances in Workroom Air Adopted by ACGIH for 1980." The monitor is recommended for STEL sampling If, during the 15 minute sampling period, the monitor will collect a minimum of 10 micorgrams of the contaminant when sampling at the STEL concentrations. E. Unsuitable Compounds The OVM is not recommended for the compounds listed below because of adverse or inadequate interactions with the sorbent material. This list Is representative of classes of compounds not suitable for use with the OVM. Compounds not on this list or the Compound Guide should be handled by consultation with OH&SP Technical Service.

The following tables summarize the 3M monitor sampling rate, capacity, recovery coefficient and calculation constants. The analysis guide provides the necessary information to calculate the time-weighted-average concentration in parts per million (ppm) or milligrams per cubic meter (mg/m3). A. Monitor Sample Information Sampling Rate The (*) compounds in the Sampling Guide tables have been subjected to an extensive amount of laboratory work to verify the sampling rate. The sampling rates given for the remaining compounds in this table were determined from empirical relationships as outlined in a publication on Sampling Rate Validation. All sampling rates have an accuracy of 5%. The sampling rates are tabulated as either cubic centimeters/minute or micrograms/ppm-hour. Capacity The capacity of the monitor for each individual compound is a function of molecular structure, vapor pressure, environmental conditions, etc. The capacity is stated in terms of weight (milligrams). For a single contaminant, if the analyst finds the weight collected by the monitor is greater than the defined capacity, then the validity of the sample should be questioned. When sampling multiple contaminants, the combined weights of the contaminants collected should not exceed the defined value for the single contaminant with the lowest capacity. Recovery Coefficients (Desorption Efficiency) The collected sample is removed from the activated carbon wafer for analysis by desorption with carbon disulfide (CS2) or other suitable solvents. In order for the laboratory analyst to determine accurately the amount of contaminant collected by the adsorbent, it is necessary to know the efficiency of the desorption process. The recovery coefficient or desorption efficiency is determined by adding a known weight of contaminant onto the adsorbent and measuring the weight of contaminant in the desorbing solvent. The recovery coefficient is calculated by dividing the recovered weight by the known weight. It is recommended that each analytical laboratory determine recovery coefficients according to the procedure outlined by the 3M laboratory contained in the Analysis Guide as "Recommended Procedure for Determination of Recovery Coefficients." Recovery coefficients determined by the 3M laboratory are tabulated in the following tables. B. Procedure to Calculate Contaminant Concentrations The time-weighted-average concentration of the environment sampled can be calculated by knowing the length of the sampling period, the contaminant weight determined by gas chromatography, the recovery coefficient and the calculation constant either A or B. The calculation constant A is used to calculate the concentration when expressed in units of milligrams per cubic meter (mg/m3) and constant B when expressed in units of parts per million (ppm). The calculation constant A and B have been determined for every contaminant in the Analysis Guide by the following expressions: A = 1000 Sampling Rate B _ 1000 x(24.45) (Sampling Rate) x (Molecular Weight) 1 3M 002259 The contaminant concentration can be calculated with the following information: Sampling Information Contaminant Length of Sampling Period (min.) t Contaminant Information from Tables in Analysis Guide Calculation Constant A or B Analytical Results Contaminant weight recovered W (Micrograms) Recovery Coefficient (r) The time-weighted-average concentration in milligrams per cubic meter of the contaminant in the environment sampled can be calculated from the following expression: C(mg/m3) = W (microgmms) r x t (minutes) xA The time-weighted-average concentration in parts per million (ppm) of the contaminant can be calculated from the following expression: C(ppm) = W (micrograms) rxt (minutes) xB The above expressions calculate the time-weighted-average concentrations at a sampling temperature of 25C (298K) and pressure of 760 mm. When sampling at other environmental conditions, the above expressions need to be corrected only for variations in temperature. The above expressions can be multiplied by the following temperatures correction factors (CFT) for samples collected at temperatures other than 25C (77F).
