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.
