Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Coated XAD-2 Tube (150/75 mg sections, 20/60 mesh) Coated with 10% (w/w) 2-(Hydroxymethyl)piperidine
    analytical solvent: Toluene
    maximum volume: 240 Liters
    maximum flow rate: 1.0 L/min
    current analytical method: Gas Chromatography; GC/NPD
    method reference: OSHA Analytical Method (OSHA 61)
    method classification: Fully Validated
    note: OSHA personnel may obtain sampling tube from the Salt Lake Tecnical Center. When relative humidity at sampling site is low, reduce maximum sample size to 120 Liters and sampling rate to 0.5 L/min.
