Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):
  • sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 micron in series with a Charcoal Tube (100/50 mg sections, 20/40 mesh)
    maximum volume: 480 Liters  
    minimum volume:
    400 Liters   
    maximum flow rate:
    1.0 L/min
    current analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 1 (NIOSH S-187)
    method classification: Fully Validated
    note: The filter is used to trap particulate Tellurium compounds that may be present.
Secondary Laboratory Sampling/Analytical Method (SAM2):
  • MIRAN 1A & 1B: MIN. Det. Con. 0.08 ppm at 13.4 um
