Primary Laboratory Sampling/Analytical Method (SLC1):
sampling media: Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns preceded by 10 mm Nylon Cyclone
maximum volume: 816 Liters
maximum flow rate: 1.7 L/min
current analytical method: Gravimetric
method reference: 11, 12
sampling analytical error: 0.10
method classification: Fully Validated
note: If the gross weight sample yields a concentration below the standard for the air contaminant, do not submit the sample to the Salt Lake Technical Center for analysis. If a gravimetric analysis is not sufficient, submit + the filter to the Salt Lake Technical Center for XRD analysis for quartz (OSHA Method ID-142). Submit bulk sample in separate package when quartz analysis is requested.
