Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns in series with Midget Fritted Glass Bubbler (MFGB) containing 15 mL Deionized Water
    maximum volume: 48 Liters
    maximum flow rate: 0.2 L/min
    current analytical method: Colorimetric
    method reference: 1 (NIOSH S-257)
    method classification: Fully Validated
    note: Submit as a separate sample. Air being sampled should not pass through any hose or tubing before entering filter holder. Use a stainless steel screen backup pad in the filter cassette instead of a cellulose membrane.
