Sampling and Analysis of Four Organic Compounds Using Solid Sorbents, No. 1.
NIOSH 1974 Sep:132 pages
NIOSH sponsored research on solid sorbent sampling methods and gas chromatographic analytical methods for the determination of phosgene (75445), acrylonitrile (107131), nitroglycerin (55630) and ethyleneglycol-dinitrate (628966), and methyl-chloride (74873) in industrial environments is described. It was noted that solid sorbents would be desirable for personal sampling pumps for collecting air samples for transport to the analytical laboratory. Suitable solid sorbents were found for all substances except phosgene. The vapors of the nitrate esters were collected on a porous polymer, desorbed by extraction with ethanol (64175), and determined by electron capture gas chromatography. Acrylonitrile was collected on a activated carbon (7440440) derived from Saran (8013772) pyrolysis, desorbed by extraction with methanol (67561), and determined by flame ionization gas chromatography. Methyl- chloride was collected on an activated carbon similar to that used by NIOSH for collection of organic solvent vapors, desorbed with methanol, and determined by flame ionization gas chromatography. Evaluation of the sampling and analytical systems for each substance indicated that each met NIOSH standards for accuracy and precision.
