Title:
ION CONCENTRATION ANALYZER
Document Type and Number:
Japanese Patent JPH04258753
Kind Code:
A
Abstract:
PURPOSE: To measure the concentration of measured ions even if interfering ions are mixed in a sample.
CONSTITUTION: A measured-ion electrode 17 measuring the concentration of measured ions contained in a measured liquid 7, an other-ion electrode (interfering-ion electrode) 18 measuring the concentration of preset ions other than the measured ions contained in the measured liquid 7, and an arithmetic section (comparing arithmetic section) 5 calculating the concentration of the measured ions contained in the measured liquid 7 based on the measured values of the other-ion electrode 18 and the measured-ion electrode 17 are provided.
