QUADRUPOLE MASS SPECTROMETER, QUADRUPOLE MASS SPECTROMETRY METHOD, AND PROGRAM STORAGE MEDIUM STORING PROGRAM FOR QUADRUPOLE MASS SPECTROMETER

摘要

A filter unit 3 having an ion source 1 from which a sample is ionized, a quadrupole 31 , mass separation of ions generated from the ion source 1 , and ions passing through the filter unit 3 . By controlling the detector 5 that detects , and a filter voltage composed of a high frequency voltage and a DC voltage applied to the quadrupole 31 , the ions incident on the filter unit 3 are not incident on the detector 5 . A filter voltage controller 62 for switching between a blocking mode that does not, and an incident mode in which ions incident on the filter unit 3 are made incident on the detector 5, and the output of the detector 5 in the cutoff mode Based on the baseline calculation unit 63 for calculating a baseline based on , the output of the detector 5 in the incident mode and the baseline calculated by the baseline calculation unit 63, An analysis unit 65 for outputting analysis results is provided.
