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.

The autosampler is used to automate the process of entering samples of liquid consistency into chromatographs of the line "Kristallux", "Crystal", series "Color", LHM. The autosampler is compact in size and easy to operate. The device is compatible with different models of chromatographs and is suitable for many studies. When the device is working with the Crystallux series chromatographs, the autosampler can be controlled using the chromatographic equipment software, while no additional programs are required.

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).
