In an imaging mass spectrometer including a data processing device according to the present invention, a regression analysis executor (16) executes PLS using mass spectrum data and reference image data for each measurement point and calculates a regression coefficient reflecting the similarity of the distribution for each m/z value. An m/z value search section (17) selects m/z values in descending order of regression coefficients, but in each search m/z range obtained by dividing the entire measurement m/z range for each predetermined width, excludes a search m/z range including one m/z value already selected from the search target. Since the peak originating from a certain compound and its isotope peak fall within almost one search m/z range on the mass spectrum, the process described above can avoid selection of the m/z value of ions originating from a certain compound and the m/z value of ions originating from its isotope in duplicate as an m/z candidate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data processing device for imaging mass spectrometric analysis","description":"The efficiency and accuracy of search for a compound exhibiting a distribution similar to that of a reference image such as an optical microscope image are improved in imaging mass spectrometric analy","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11276565","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.
