Based on the three-dimensional data, a data matrix creator (41) creates data matrix X in which intensity data are arranged in N rows which differ from each other in m/z value and M columns which differ from each other in retention-time value. A matrix factorization executer (42) determines an N×K spectrum matrix S and K×M profile matrix P (where K is a natural number) by matrix factorization based on data matrix X so that this matrix X is approximated by product SP of the matrices S and P. An m/z detector (43) detects m/z of a precursor ion originating from a sample component from the values of the matrix elements in each column of matrix S. A retention time detector (44) detects the retention time of a sample component from the values of the matrix elements in each row of matrix P. Based on the m/z and retention time, an MSm analysis execution condition determiner (45) determines an execution condition of an MSm analysis including the selection and fragmentation of a precursor ion of a sample component. An MSm analysis executer (52) makes the mass spectrometer execute an MSm analysis based on the execution condition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chromatograph mass spectrometer","description":"In order to appropriately set MSm analysis conditions, an MSm-1 analysis executer (51) makes a mass spectrometer (20) perform an MSm-1 analysis (where m is an integer from 2 to n) to acquire three-dim","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11988653","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
