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.

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.

To determine small concentrations of substances, in some cases it is impossible to do without their concentration in special traps. An example of the need for such concentration is the determination of impurities in permanent gases (Ne, He, H2, Ar, O2, N2, Kr, Xe), the concentration of impurities is less than 1 ppm. Considering that these impurities can be not only hydrocarbons, but also permanent gases themselves, the use of direct detection of impurities by a catarometer is impossible. It is also not always possible to use highly sensitive but expensive detectors (GID, EDD, etc.). TECHNICAL CHARACTERISTICS The volume of the trap is 5 ml. The volume of the Dewar vessel (serial metal thermos) is 1200 ml. The concentration temperature range is from minus 88.6 (ethane) to minus 269 °C (helium).
