Choice of the Optimal Output Channels Configuration in the Gas Chromatograph Detector

Abstract One of the most important chromatograph elements is a detector. This article describes the way to increase the sensibility of thermal conductivity detector - the most frequently used detector - that is being developed by Chemistry Department in cooperation with other departments at Samara University. The purpose of the research is choice of the optimal output channels configuration in the gas chromatograph detector that provides uniform temperature fields distribution at constant gas-flow rate. Two options of the output channels configuration were proposed. The temperature fields in gas chromatograph detector were calculated by ANSYS software package for mixtures with various concentrations of air and hydrogen.
