Plasma insulating oil chromatographic analysis device with automatic calibration function and method

According to the plasma insulating oil chromatographic analysis device and method with the automatic calibration function, firstly, high-concentration gas is used for flushing a pipeline, interference of residual gas in the pipeline is eliminated, a circulation pipeline rapidly adsorbs a large amount of impurity gas, the adsorption amount reaches or exceeds the adsorption saturation amount under the calibration concentration, and then the pipeline is subjected to automatic calibration; and then the gas with the calibrated concentration is introduced for 10 minutes, so that the pipeline is subjected to adsorption saturation under the concentration, the analyzed gas concentration value is ensured to be a label value, the reliability of a calibration result is improved, and the analysis and detection precision is improved. According to the invention, bottle gas with known concentration can be diluted according to pressure through the two buffer tanks, and calibration gas containing impurity gas with different co
