What is Thermal Conductivity Detector Overview about?

The Thermal Conductivity Detector (TCD) is a universal detector that can detect many compounds based on differences in thermal conductivity between the carrier gas and sample gas. The TCD works by heating two channels - one with just carrier gas and one with the sample-carrier gas mixture. It measures the voltage difference produced from differences in thermal conductivity, providing a signal proportional to sample concentration. Key factors for the TCD response are the detector block temperature, carrier a
