According to the requirements of the standards, the cooler is included in the list of equipment for determining humidity with pre-drying. Usually, grain samples after preliminary drying are cooled in the laboratory room to ambient temperature. However, with such cooling, the ambient temperature reaches only the surface layers of the samples, which affects the results of the analyses. The principle of operation of the cooler is based on blowing sample canopies in mesh buckets placed on a stand by a fan rotating at high speed. Advantages: Rapid cooling of samples. Stable moisture distribution. Allows you to significantly improve the accuracy of the results of determining humidity.

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.

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.
