Title:
MASS SPECTROMETRY DEVICE AND MASS SPECTROMETRY METHOD
Document Type and Number:
WIPO Patent Application WO/2020/031703
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a mass spectrometry device which is inexpensive yet capable of obtaining a quantification result with high precision. A short-section measurement instruction unit 101 instructs a detector 9 to perform measurement in multiple short sections 5 in a channel 4 and stores signals detected by the detector 9 into a data storage unit 102, the signals are added up by a short-section signal amount addition unit 103, and the variation of the added signals is calculated by a signal variation calculation unit 104. A signal variation evaluation unit 105 evaluates the variation of the signals in each short section 5 in the same channel 4. When the evaluation result indicates a stable state, an operation control unit 106 controls operation of an ion source 6 and continues with the measurement without issuing a warning. When the evaluation result indicates an unstable state, a warning is issued during the measurement or after the measurement.
