Title:
SOLUTION ANALYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/169444
Kind Code:
A1
Abstract:
This invention addresses the problem of providing a solution analysis system with which analysis can be implemented simply and quickly and that is capable of continuous monitoring and of individually analyzing the ion concentrations of a plurality of ion species. The problem is addressed by a solution analysis system that is characterized in that: an impedance measurement device 1 carries out multivariate analysis on frequency-resistance characteristic data that has been detected using an impedance method for a known solution having a known concentration of a specific ion species; a plurality of constants corresponding to frequency measurement points are determined; of the plurality of determined constants, characteristic constants unique to the specific ion species and the frequencies corresponding to the constants are made to be constant-frequency correspondence information; and the impedance measurement device 1 calculates the concentration of the specific ion species in an unknown solution for which the concentration of the specific ion species is unknown on the basis of measurement data obtained through resistance measurement of the unknown solution using the impedance method and the information about the correspondence between the determined characteristic constants unique to the specific ion species and frequencies.
