Abstract
IN a recent communication to Nature, Drs. Evrard, Thevelin and Joossens1 described their experience with a self-sustained discharge detector for chromatographic analysis of permanent gases. Argon containing 200 p.p.m. of ethylene was used as carrier gas, a mixture similar to that described elsewhere by Willis2 for detecting atmospheric gases with an ionization detector containing a radioactive source. In both these methods, permanent gases quench the current flowing in the detector.
