The metering valve for the introduction of gas samples is designed for the introduction of gas under excessive pressure into the chromatograph. Cranes differ in the number of moves (4, 6, 8, 10, 12) and have two provisions "Selection" — "Analysis". In addition to dosing, cranes can be used to switch chromatographic columns, elements of gas circuits, etc. The tap can be installed either on the side panel of the chromatograph, or directly into the analytical module instead of, or together with the evaporator of the chromatograph, while it is used as a back-purge tap or for hot sample entry.

When analyzing gases dissolved in transformer oil using the ARP method (equilibrium vapor analysis), it is necessary to first fill a syringe with transformer oil with a carrier gas, and then, after achieving an equilibrium distribution of gases dissolved in oil between the liquid and gas phases, introduce the gas phase into the chromatograph (blow out the doses of the chromatograph dispenser tap). Moreover, the operations of filling the syringe and entering the sample are performed without air access. When filling the syringe, it is possible to fix the syringe stem at a certain volume. technical specifications The volume of syringes is 20 or 50 ml. The pressure at the outlet of the syringe filling line with argon is 0.5 atm. The range of ratios of volumes of the gas phase and oil (Vg/Vm) is from 0 to 1.5.

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.
