Abstract: This paper summarizes the current situation of odor control of automobile parts. The control methods mainly include subjective odor evaluation of professional odor personnel, TVOC detection and GCO-MS. In view of the limitations of the above methods in the field application, this paper introduces a rapid mass spectrometry technology using portable mass spectrometer to detect odor, and shows the practical application of this technology in the field of automobile odor detection. Through the analysis, the paper draws a conclusion: this method is simple to operate, the test results show good linear consistency, has low requirements for the test environment and short test time, and can realize the real-time monitoring of the odor status of parts before going online.
