During the gas-phase purification, the mass-to-charge ratios of precursor ions within at least a selected range are selectively changed allowing ions having similar unmodified mass-to-charge ratios to be separated before further isolation, fragmentation or analysis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gas-phase purification for accurate isobaric tag-based quantification","description":"Described herein are mass spectrometry systems and methods which improve the accuracy of isobaric tag-based quantification by alleviating the pervasive problem of precursor interference and co-isolati","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9698001","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.
