特徴とする質量分析計。[Claims for Utility Model Registration] 1. A mass spectrometer consisting of a GC-MS and an EI/CI automatic switching device, characterized in that the EI/CI is alternately switched in synchronization with the appearance peak of total ions. 2. The mass spectrometer according to claim 1, which normally performs measurement in EI mode, and performs alternate EI/CI measurement only when a peak appears on the total ion. 3 In claim 1, EI mode measurement is normally performed, and when the peak that appears on the total ion begins to fall, CI mode is taken in once or several times, and the original EI mode measurement is performed again. A mass spectrometer characterized by:
