Title:
ELECTROLYTE-CONCENTRATION MEASURING SENSOR
Document Type and Number:
Japanese Patent JPS61241656
Kind Code:
A
Abstract:
To determine electrolyte concentrations in aqueous solutions, ion-selective electrodes, inter alia, are used, that is to say electrodes whose ion-selective layer only allows particular ions through. The potential difference set up is a measure of the electrolyte concentration in the sample. In medical applications, in particular, it is a disadvantage that these electrodes are relatively large, that the electrolyte bridge is susceptible to interference and that a reference electrode is required.
To avoid these disadvantages, according to the invention, a potential-sensitive fluorescence indicator whose fluorescent intensity is measured and is used to determine the electrolyte concentration is provided at the ion-selective layer.
