Monitoring Methods used by OSHA

Laboratory Sampling/Analytical Method:

  • sampling media: Glass Fiber Filter (37 mm open face) coated with 1.0 mg 1-(2-pyridyl)piperazine
    analytical solvent: (90:10) Acetonitrile:Dimethylsulfoxide
    maximum volume: 15 Liters
    maximum flow rate: 1.0 L/min
    current analytical method: High Performance Liquid Chromatography; HPLC/UV/FLU
    method reference: OSHA Analytical Method (OSHA PV2125)
    method classification: Partially Validated
    note: OSHA personnel may obtain filters from SLTC. Keep filters refrigerated until use. Results may not reflect accurate exposures to the polymeric forms of isocyanates.
