This method is used for the determination of 1,1,2-trichloro-1,2,2-trifluoroethane. The sample is collected on charcoal sorbent tubes, desorbed in carbon disulfide, and analyzed using GC/FID. The working range is 10 to 18000 mg/m³ (1.3 to 2350 ppm) for a 1.5 L air sample. This method may be used with diffusive sampler collection, but a larger volume may be needed for desorption. NOTE: This method is a revision of NIOSH 3rd ed. Method 1020 (8/15/90). This method was updated for sequences 6937, 6956, and 6916A. Method S129 was originally evaluated under NIOSH Contract CDC-99-74-45.
