Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):
  • sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns
    maximum volume: 960 Liters
    minimum volume: 480 Liters
    maximum flow rate: 2.0 L/min (TWA)
    maximum volume: 30 Liters
    minimum time: 15 Minutes
    maximum flow rate: 2.0 L/min (Ceiling)
    current analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 2 (OSHA ID-121)
    sampling and analytical error: 0.11
  • method classification: Fully Validated
    alternate analytical method: Inductively Coupled Argon Plasma; ICP/DCP-AES
    method reference: 2 (OSHA ID-125G & ID-206)
    sampling and analytical error: 0.11
    method classification: Fully Validated
    note: If the filter is not overloaded, samples may be collected up to an 8-hour period when determining a PEL concentration. Analytical method does not distinguish between dust and fume.
