A mass difference between a product ion, originating from the unidentified substance and having a partial structure including a structural change site, and a product ion, originating from the original substance and having a partial structure prior to the structural change, is equal to the mass difference between the original substance and the unidentified substance. Therefore, when pairs of product ions each having such a mass difference are selected to be compared with partial structures obtained from the known structural formula of the original substance, a minimum common partial structure having the structural change site is obtained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mass analysis data analyzing method and apparatus","description":"A method and apparatus for estimating the structure of an unidentified substance produced from an original substance having a known structural formula through partial structural change caused by metab","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9638629","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.
