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 pyrolytic gas chromatography method is widely used in the study of polymer materials, plastics, rubbers, rubbers, paints and other high-molecular compounds of natural and artificial origin. The method is based on thermal decomposition of sample samples in an inert medium (without oxygen access), followed by chromatographic separation and analysis of the formed volatile compounds. Thus, the resulting pyrogram allows us to judge the composition of the original sample. Pyrolysis is also used in geochemical studies. Technical specifications The volume of the capsule is 56 ml. Pyrolysis temperature — from 200 to 1000 °C. The error of maintaining the temperature is not more than 1.0 ° C. The heating time of the sample to the pyrolysis temperature is no more than 2 seconds. The cooling time of the capsule when moving from the hot zone to the cold zone after pyrolysis is no more than 10 seconds. The time of continuous operation in the pyrolysis mode is no more than 60 seconds. Electric power supply from the AC network with voltage (220index) V, frequency (50 ± 1) Hz. Power consumption — no more than 100 VA. Overall dimensions of the control unit (width ×depth×height) — 210×190×100 mm. Overall dimensions of the input node (width× depth×height) — 90×135×160 mm. The weight of the control unit is not more than 2.5 kg. The weight of the input node is not more than 0.9 kg.

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.

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.
