“ Breakthrough (effluent = 5% of test concentration) occurred after sampling for 60 min at 0.046 L/min from an atmosphere containing 14500 mg/m3 1,1,2-trichloro-1,2,2-trifluoroethane in dry air. Desorption efficiency for 18 samples of SKC lot 105 activated coconut charcoal spiked with 5.6 to 23 mg 1,1,2-trichloro-1,2,2-trifluoroethane averaged 1.01 with = 0.02. ”

“ Carbon disulfide is toxic and a serious fire and explosion hazard (flash point = –30 °C) . 1,1,2-Trichloro-1,2,2-trifluoroethane is a narcotic [4] . Work with these compounds only in a hood. SAMPLING: 1.Calibrate each personal sampling pump with a representative sampler in line. 2.Break the ends of the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. 3.Sample at an accurately known flow rate between 0.01 and 0.05 L/min for a total sample size of 0.1 to 3 L. 4. ”

“ Method S129 was issued on May 9, 1975 [3] , and validated with generated atmospheres using calibrated syringe drive and independent verification by gas chromatography [2] . Average recovery was 100.3% (18 samples) in the range 3300 to 14200 mg/m3 for 1.5-L samples. ”
