The lithium ions measuring method is characterized by contacting the specimen including serum and plasma test sample with an aqueous solution of a lithium reagent composition comprising a tetraphenyl porphyrin compound, a pH regulator and a pH buffer, by irradiating or expose the resulting solution with white light, and by detecting change in color tone by a visual observation or by detecting the sensitivity by a colorimeter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lithium measurement method","description":"To provide to a method for measuring and examining lithium ions in an aqueous solution of a specimen such as biomaterials or environment samples, by using a lithium reagent composition as a coloration","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9689794","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.
