Further, a mobile phase is sent while a setting value of a concentration of the second solvent in the mobile phase is changed over time with the separation column provided on an analysis flow path, and an actual concentration of the second solvent in the mobile phase is found based on a detection signal of the detector when the mobile phase is sent at each setting value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of measuring accuracy of concentration in sending liquid in gradient and liquid chromatograph having function of executing method","description":"An organic solvent containing liquid that does not include a component to be detected by a detector is used as a first solvent, and an organic solvent containing liquid that includes the component to ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11486863","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.
