In the present invention, a packing material for size exclusion chromatography is obtained by a production process including polymerizing glycerol 1,3-dimethacrylate and glycidyl methacrylate in the presence of a polymerization initiator, hydrophilizing the resulting porous particles made of a copolymer using a sugar alcohol, and then opening the rings of remaining glycidyl groups using a mineral acid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Packing material for size exclusion chromatography and method for producing the same","description":"An object of the present invention is to provide a packing material suitable for use as a packing material for size exclusion chromatography for fractionation that requires large-scale treatment, the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11285404","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.
