Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns
    maximum volume: 960 Liters
    maximum flow rate: 2.0 L/min (TWA)
    maximum volume: 30 Liters
    maximum flow rate: 2.0 L/min (STEL)
    current analytical method: Gravimetric
    method reference: 11, 12
    sampling and analytical error: 0.10
    method classification: Fully Validated

    current analytical method: Ion Specific Electrode; ISE
    method reference: 2 (OSHA ID-164)
    method classification: Partially Validated

    current analytical method: Ion Chromatography; IC/Conductivity
    method reference: 2 (OSHA ID-188)
    sampling and analytical error: 0.08
    method classification: Fully Validated
    note: 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.

Wipe Sampling Method:

  • sampling media: Whatman smear tab
    analytical solvent: Deionized Water
