Abstract:

Halogenated organic solvents are of particular concern in closed atmospheric situations such as nuclear submarines, spacecraft, and hyperbaric chambers due to their corrosive and toxic potential. A gas chromatographic on- column concentrating technique has been developed for the analysis of halocarbons in atmospheric gas mixtures, thus eliminating the use of cold traps. An important part of this analytical system is a coulometric detector which is specific for chlorinated, brominated, or iodated hydrocarbons. By making use of this specific detector and the on-column concentrating technique, gas samples can be analyzed quantitatively for chlorinated contaminant compounds at concentrations as low as 10 to 20 parts per billion by volume.
