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.
