| 摘要 |
<p>Disclosed is an electrochemical cell containing two or more electrodes wherein the half-cell potential of at least one electrode is determined by the concentration of a specific ion anticipated to be present in all test solutions, said ion concentration being measured in the cell by a first electroanalytical technique that does not depend on a known reference electrode potential, such that said electrode, its half-cell potential being calculable from the measured ion concentration, can then serve as a reference electrode in one or more subsequent electroanalytical techniques that do depend on a known reference electrode potential, said subsequent technique or techniques being carried out in the same cell.</p> |
