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.

TDS-2 is a syringe (see Fig. 1), which is installed on the evaporator of the chromatograph. The device is equipped with a crane that cuts off the carrier gas line when removing the rod with the sorption tube from the thermal desorber. When the tap is open, the stem is lowered to the lower position and the sorption tube is inserted into the evaporator brought to the desired temperature. In the conditions of the upper position of the rod, it is also possible to displace air by purging the sorption tube with a carrier gas.
