Title:
MASS SPECTROMETRY SYSTEM, PROCESSING DEVICE, AND ANOMALY DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286612
Kind Code:
A1
Abstract:
In order to facilitate detection of an anomaly in a liquid chromatography mass spectrometry device, the present invention is characterized by comprising: liquid chromatography having a plurality of flow paths, a mass spectrometry device (110), and a processing device (2) that obtains a signal intensity that is a result of measurement of a substance from the mass spectrometry device (110). The present invention is also characterized in that: a separation column (105) is provided in each of the plurality of flow paths; the plurality of flow paths are arranged in parallel; a flow path that is to be connected to the mass spectrometry device (110) is selected from the plurality of flow paths by a selector valve (106); in each of the plurality of flow paths, a predetermined substance is caused to flow together with a solution; the predetermined substance is measured using the mass spectrometry device (110); and the processing device (2) determines an anomaly in LC/MS1 on the basis of a signal intensity obtained as a result of measurement by the mass spectrometry device (110), and outputs the result of the determination to an output device, for each of the plurality of flow paths.
