DETERMINATION OF TRACE QUANTITIES OF HALOGENATED HYDROCARBONS IN GAS SAMPLES

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.
