Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Glass Fiber Filter (37 mm)
    analytical solvent: Isooctane
    maximum volume: 180 Liters
    maximum flow rate: 1.5 L/min
    current analytical method: Gas Chromatography; GC/ECD
    method reference: 1 (NIOSH S-283)
    sampling and analytical error: 0.14
    method classification: Fully Validated
    note: Within 1 hour after the sample has been collected, transfer the filter to a clean screw cap vial.

Bulk Method:

  • Limit the amount of bulk submitted to one gram or one mL.
