After the comprehensive analysis of the traditional degassing methods of analysis for insulating oil chromatographic, a novel automatic degassing device based on headspace bottle withdraw was introduced from both the theoretical and practical aspects. The device was equipped with pumping and injection part, and it could be connected to chromatographic instrument. The device not only retained the advantages of traditional mechanical vibration method, but could complete the process of degassing and sample injection automatically. The device can get the position of the oil sample accurately under the help of intelligent control system. Microcomputer will control the process of heating, temperature control, timed oscillation and delayed alarm automatically. In order to ensure the practicability and accuracy of this equipment, a series of experiments was carried out to verify the temperature precision and accuracy, and oil sample accuracy. The experiment results indicate that the properties of equipment can meet the design requirements. The development of this device is of popularization value, which will play a positive role in promoting the automatic analysis of insulating oil chromatography.
