In the present invention, online pretreatment and separation of a sample containing highly lipophilic components in a sample to be analyzed are performed by a multidimensional chromatography system. The multidimensional chromatography system includes a supercritical chromatography part and a reverse phase liquid chromatography part sequentially connected, the reverse phase liquid chromatography part including one or more reverse phase liquid chromatography columns, and the supercritical chromatography part including a supercritical mobile phase, a modifier, and a supercritical packed column."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Analysis system and method for rapidly detecting vitamin d in an oil or fat, or a biological sample","description":"The present invention relates to an analysis system that is applied to rapid automatic analysis and detection of highly lipophilic components and a method for rapidly detecting vitamin D in an oil or ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11946911","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.
