Self-sustained Discharge Detector for Chromatographic Analysis of Permanent Gases

Abstract

A REVIEW of the ionization detectors for gas chromatography has been made by Lovelock1. While primarily designed for the sensitive detection of organic gases and vapours, Lovelock's2 radioactive argon ionization detector has been adapted by Willis3 to the detection of permanent gases. The latter arrangement permitted the use of a commercially available instrument, with only a slight alteration in the nature of the carrier gas. Use is made of the property of permanent gases to quench the ionization current flowing through the radioactive ionization detector, when the argon supply is contaminated by a small amount of ionizable organic impurity. Theoretical considerations have been presented by Lovelock1.
