TCD Gas Chromatograph
Analysis of H2, O2, Ar, N2, CH4, CO, CO2, Kr, Ne, Xe, He in % level.
The TCD Gas Chromatograph is not as sensitive as other detectors but it is non-specific and non-destructive. A TCD detector consists of an electrically-heated wire or thermistor (tungstenrhenium wire). The temperature of the sensing element depends on the thermal conductivity of the gas flowing around it.
