Monitoring Methods used by OSHA

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: Field method. If the filter is not overloaded, samples may be collected up to an 8-hour period. Submit as a separate sample only if the gross weight of the sample yields an air concentration greater than the PEL. When the analysis of a compound is requested an analysis is performed for total ammonia and reported as the compound. The analytical method does not distinguish between dust and fume.
