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
    minimum volume: 480 Liters
    maximum flow rate: 2.0 L/min
    current analytical method: Gravimetric Analysis
    method reference: 11, 12
    sampling and analytical error: 0.10
    method classification: Fully Validated
    note: Field method. If the gross weight of the sample yields a concentration below the standard for the air contaminate, do not submit sample to SLTC for analysis. If the filter is not overloaded, samples may be collected up to an 8-hour period.

  • alternate analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 2 (OSHA ID-121)
    method classification: Not Validated
    note: Submit as a separate sample. An elemental analysis for Tellurium or Bismuth is performed and reported as the compound.
