During a measurement, the preparative separation of an eluate and the preparation of fractionated samples are not performed within a period of time which has been judged to be useless based on the fractionated sample useful information. By selecting fractionated samples at each dimension of the multi-dimensional LC, the number of fractionated samples to be eventually subjected to mass spectrometry can be significantly reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid chromatograph mass spectrometer","description":"In a liquid chromatograph mass spectrometer (LC/MS) for performing mass spectrometry of fractionated samples prepared with a multi-dimensional LC or similar LC with high separatory capability, fractio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10520479","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.
