The content of corrosive sulfur dibenzyldisulfide (DBDS) in insulating oils was tested by gas chromatography-mass spectrometer (GC-MS), and the influencing factors of detection were investigated. The quantitative detection methods of DBDS, which include external standard method and internal stan-dard method, were built by exploring the experimental condition. The method provides a new method and a new idea for the high efficient detection of organic molecule in insulating oils, and also provides references for establishing quantitative detection standards of corrosive sulfur in insulating oils in China.
