The combined pump-injector valve permits injection of nanoliter-sized samples into a chromatographic column, which is sealed during loading of the sample and filling of the pump, such that complete analyses can be completed with microliters of mobile phase with nanoliters of a sample. The pump-injector valve system further includes a pressure sensor external the barrel of the pump and may include an interim position intermediate loading and injection where the contents of the barrel may be pressurized to a desired pressure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pump and injector for liquid chromatography","description":"A combined pump-injector valve system utilizing a monolithic body to provide the barrel of the pump and as the stator of the valve, thus eliminating any need for connections between a pump and a valve","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9822772","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.
