Patent number: 11990327Abstract: In a mass spectrometer employing laser ionization to ionize a sample, a known sample is irradiated with laser light multiple times, and multiple sets of profile data are acquired each of which is a spectrum showing the relationship between the m/z values and intensities of ions generated from the known sample by one laser irradiation (Step S11). Those sets of profile data are sorted into groups so that one or more sets of profile data are included in each group (Step S12). For each group, a peak list is created which describes the m/z value and intensity of each peak originating from the known sample based on the one or more sets of profile data included in the group (Step S13). A discriminant model for discriminating an unknown sample is created using the peak lists of the plurality of groups and information concerning the kind of the known sample as training data.Type: GrantFiled: February 18, 2022Date of Patent: May 21, 2024Assignee: SHIMADZU CORPORATIONInventors: Tatsuki Okubo, Yoshihiro Yamada
