Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):
  • sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 microns
    analytical solvent: Deionized Water
    maximum volume: 960 Liters
    minimum volume: 480 Liters
    maximum flow rate: 2.0 L/min
    current analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 2 (OSHA ID-121)
    sampling and analytical error: 0.12
    method classification: Fully Validated
    note: Submit as a separate sample. If the filter is not overloaded,samples may be collected up to an 8-hour period. When analysis of a compound is requested, an elemental analysis for Chromium is performed and reported as the compound.
