LITHIUM MEASUREMENT METHOD

摘要

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 reaction reagent and by visual observing or a simple a colorimeter. 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.;

1. Method for measuring lithium, characterized by contacting a specimen with an aqueous solution of a lithium reagent composition comprising a compound represented by following structural formula in which all hydrogens bonded to carbons of a tetraphenyl porphyrin are replaced by fluorine:a pH regulator and a pH buffer, by irradiating 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.
