Monitoring Methods Used by OSHA
Analyte code (IMIS no.)	9040 (resp); request using analyte code 9130
Sampling group
Sampler/Sampling media	Tared low-ash 37 mm PVC filter, 5 microns, preceded by 10 mm nylon Dorr-Oliver cyclone for respirable samples. [SLTC108]
Sampling time^*	240-480 min
Sampling volume (TWA)^*	816 L
Sampling flow rate (TWA)^*	1.7 L/min ±5%
Sampling volume (STEL/Peak/C)^*
Sampling flow rate (STEL/Peak/C)^*
Analytical method instruments	Gravimetric
Method reference	OSHA PV2121 (partially validated)
Notes	If the filter is not overloaded, samples can be collected up to an 8-hour period. If the net weight of the sample yields a concentration below the PEL after considering the associated SAE , the SLTC will perform no further work on the sample and the sample air concentration will be reported as the calculated gravimetric air concentration. If the net weight corresponds to an amount greater than the PEL value after considering the associated SAE, the sample may be analyzed for the applicable component and appropriate results will be reported.
Special requirements	For respirable samples, the sampling media must be preceded by a 10 mm nylon Dorr-Oliver cyclone.
