Abstract
The present invention announces a method for extending the storage life of a test reagent for quantification of ionic components in samples by using an anion sensor. The purpose of the present invention is to provide an anion sensor, wherein the storage life of the anion sensor itself may be extended, to thereby extend the storage life of the anion sensor beyond that of conventional anion sensors. According to the present invention, through adjustment of the pH of the internal solution (internal gel liquid), it is possible to provide an anion sensor that maintains consistent performance, and has longer storage life.
