Inert gas analysis method

The invention belongs to the technical field of gas analysis, and particularly relates to an inert gas analysis method which is provided with an inert gas analysis system. The inert gas analysis system comprises a man-machine interaction module, a data processing module, a data acquisition module, a first analysis module, a second analysis module, a third analysis module, a fourth analysis module, a metal element trapping module, a fifth analysis module and a calibration gas generation module, and all the modules are orderly and reasonably connected to form the complete inert gas analysis system. Basic information of gas to be detected is input through the man-machine interaction module, the control module sends a command to the analysis module I, the analysis module II, the analysis module III, the analysis module IV, the metal element trapping module and the analysis module V, and the analysis modules and the metal element trapping module complete respective tasks respectively. And the data analysis module
