Titel
New electrolytic conductivity detector for capillary gas chromatography. Analysis of chlorinated hydrocarbons
Abstract
An electrolytic conductivity detector for high resolution capillary gas chromatography has been constructed. By avoiding phase separation and with direct passage of the gas-liquid mixture through the conductivity cell, a high speed of response could be achieved. Doping of the auxiliary gas with vinyl chloride as a hydrogen chloride generator results in peaks free from tailing even at trace concentrations in the halogen-selective mode of operation. The detection limit for chlorine is 1.5*10 -12 g/sec. The detector response is directly proportional to the chlorine content of the sample over a dynamic range larger than five orders of magnitude.
