| titleOfInvention | Mass spectrometer and mass calibration method in mass spectrometer |
| abstract | The matrix-derived peak information acquisition unit (31) creates a peak list summarizing various ions derived from the matrix and their theoretical m / z values based on the result of analyzing the sample of the matrix only, and the matrix-derived peak information storage unit (31). Store in (32). When the measured mass spectrum of the target sample is obtained, the mass calibration reference peak detector (33) uses the peak list corresponding to the matrix used in the analysis to display the matrix-derived ions appearing in the measured mass spectrum. Identify the peak. The mass calibration information calculation unit (35) obtains mass calibration information from the measured m / z value of the identified peak and the theoretical m / z value, and the mass calibration processing unit (37) uses the mass calibration information. Correct the m / z value of the peak derived from the target compound on the measured mass spectrum. As a result, accurate mass calibration can be performed without using a standard substance or even when ions derived from the standard substance cannot be observed with sufficient intensity. |
