Monitoring Methods used by OSHA
Laboratory Sampling/Analytical Method:
sampling media: Coated XAD-2 Tube (150/75 mg sections, 20/60 mesh) Coated with 10% (w/w) 2-(Hydroxymethyl)piperidine. SOLVENT: Toluene
maximum volume: 240 Liters maximum flow rate: 1.0 L/min
minimum time: Minutes maximum flow rate:
current analytical method: Gas Chromatography; GC/NPD
method reference: OSHA Manual of Analytical Methods (OSHA 61)
method classification: Fully Validated
note: OSHA personnel may obtain sampling tube from SLTC. When relative humidity at sampling site is low, reduce maximum sample size to 120 Liters and sampling rate to 0.5 L/min.
