To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.
