ABSTRACT:
The concentration ratio of lithium ions to sodium ions can be determined very accurately and excellently reproducible by using an electrode for the determination of lithium ions and an electrode for the determination of sodium ions and by contacting the ion sensitive members of said electrodes with the sample solution. The two electrodes are electrically connected via an instrument for the determination of the voltage and accordingly the potential difference .DELTA. V between said two electrodes is determined. From said potential difference the concentration ratio of lithium ions to sodium ions in the sample solution can be calculated. It is furthermore possible to connect electrically the lithium electrode as well as the sodium electrode via an instrument for the determination of the voltage with a single external reference-electrode or a common-electrode and then from the two measured potential differences the potential difference .DELTA. V between the lithium electrode and the sodium electrode is calculated.
