Abstract
Improved system for gas chromatography wherein use is made of a separation column and a TCD (Thermal Conductivity Detector), characterized in that the outflow from the separation column is ionized, and the ionization takes place upstream of the TCD. The ionization of the outflow from the separation column upstream of the TCD is surprisingly found in many cases to have a favorable effect on the response of the TCD. The sensitivity of the TCD is found in many cases to increase substantially. For ionization purposes use can be made of electromagnetic radiation, ionizing radiation or pyrolysis. The degree of ionization is preferably measured by means of measuring means provided for the purpose. The response of the TCD and the measurement data obtained with the measuring means are found together to give in many cases even more and better information relating to components present in the outflow from the separation column.
