Anaerobically prepared serum samples from healthy subjects were simultaneously analysed for Ca++ in a flow-through-system of three ion selective disc-electrodes (electrochemical multimeasurementsystem). Two of the sensors contained electrically charged ligands, the third contained a neutral carrier. With neutral carriers an improvement of performance was noted in that there was a large increase in selectivity toward H+- and NH+4-ions and a distinct enhancement of reproducibility.
对来自健康受试者的厌氧制备血清样本，使用三个离子选择性圆盘电极的流通系统（电化学多测量系统）同时分析钙离子浓度。其中两个传感器含有带电配体，第三个含有中性载体。使用中性载体时性能有所改善，即对氢离子和铵离子的选择性大幅提高，重现性也显著增强。
