Full-process automatic operation method for oil chromatography test

The invention discloses an oil chromatography test full-process automatic operation method, which uses an oil chromatography test full-process automatic operation device, and comprises the following steps: introducing carrier gas for pipeline purging, and discharging the carrier gas after the carrier gas passes through a gas sample valve group to an oil sample degassing cylinder; an insulating oil sample to be detected in the oil sample injector enters the oil sample degassing cylinder through a pipeline, and is discharged after being washed; a tested insulating oil sample is sucked into the oil sample degassing cylinder, and carrier gas is introduced to remove air above the oil level in the oil sample degassing cylinder; heating and oscillating the sample oil in the oil sample degassing cylinder to form a balance gas sample to be detected, and respectively recording the pressure in the oil sample degassing cylinder before and after degassing; negative pressure is established in an inner cavity of the injecti
