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.

When determining the total gas content (air) and humidity of transformer oil, direct injection of transformer oil into the evaporator of the chromatograph is used. The sample volume is up to 25 µl, the evaporator temperature is 250-350 °C. The main problem with such an input is the protection of the chromatographic column from transformer oil. For this purpose, a special evaporator is used with the possibility of oil accumulation at the bottom of the evaporator and its subsequent discharge, and a replaceable pre-column that protects the column from oil residues that have passed the evaporator. technical specifications The volume of the evaporator is 10 ml. The number of replaceable pre—columns in the device kit is 5. The temperature of the evaporator is from 250 to 350 °C. The possibility of draining the transformer oil accumulated in the evaporator.

Selective detector for organochlorine compounds and other halogens. It is also sensitive to compounds containing oxygen, phosphorus or aromatic rings, but to a lesser extent. Paraffins and simple hydrocarbons almost do not capture electrons and are not registered. The selectivity to hydrocarbons is 108. It is available in two versions — conventional EDD and micro-EDD, mainly for capillary columns (the second version is characterized by increased sensitivity). The level of fluctuation noise is up to 300 MV, the maximum signal is up to 5 V, the design of the ECD allows the use of argon, helium, and hydrogen as a carrier gas, in addition to nitrogen. Technical characteristic: 4.0*10-15 g/s for lindane

It operates in the mode of a helium ionization detector (GID) and is considered the most sensitive device for determining permanent gases. In addition, it is able to work in the EDD mode. Technical characteristic: 2.0*10`13 g/s by. methane or hydrogen

The reverse purge valve is a 4-way valve designed to change the direction of the flow of the eluent through the nozzle column and blow off heavy components from the beginning of the column in the opposite direction into the detector. The crane is attached to the bottom panel (bottom) of the module, while taking the temperature of the column thermostat. The two upper fittings (see Fig.) are used to connect the column, the other two are connected to the evaporator and the detector.

The metering valve for the analysis of liquefied gas (KDSG) is designed for the introduction of liquefied gas or other liquid under excessive pressure into the evaporator of the chromatograph. KDSG is a 4-way crane, in which a dose of a certain volume is installed. The tap is installed on the evaporator of the chromatograph. A dose of any volume can be installed on the tap. Dose change can be performed by the operator. The amount of the dose volume is indicated on the tag. Technical specifications The dose volume is from 0.25 to 4.0 µl (at the request of the consumer, the dose volume can be increased up to 10 µl). The tap temperature is no more than 150 °C. The pressure in the crane line is not more than 0.48 MPa. The angle of rotation of the crane handle is 90 °C.

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.
