Title:
SODIUM ION DETECTION REAGENT, SODIUM ION DETECTION METHOD, AND SODIUM ION DETECTOR
Document Type and Number:
Japanese Patent JP2011043355
Kind Code:
A
Abstract:
To provide a sodium ion detection reagent capable of highly precisely detecting sodium ions even when the concentration of the sodium ions is lower in a sample; a sodium ion detection method using the sodium ion detection reagent; and a sodium ion detector.
A sodium ion detection reagent comprising a compound having calix[4]arene and a coloring organic group color-developable by proton dissociation equilibrium in the molecule is used. Specifically, a sodium ion detection method is used that detects sodium ions in a sample by measuring as an object to be measured one that has captured sodium ion by the sodium ion detection reagent through a photothermal conversion measuring method, for example.
