概述离子选择性电极是近年来新发展起来的一种分析工具。特别在六十年代中期以后,随着生产发展的需要,新的膜材料不断开拓,离子选择性电极的品种日益增多,已达数十种之多。因此过去一些专用的离子活度计如pH计和pNa计等就无法适应大多数离子选择性电极测量的需要。从而对与离子选择性电极配套的测量仪器提出了新的要求,这就是必须对大多数的离子选择性电极具有通用性:测量仪器的输入阻抗和输入电流,测量范围,测量精度,电极系数校正器的调节范
Overview Ion selective electrode is a newly developed analytical tools in recent years. Especially in the mid-1960s, with the development of production needs, the new membrane materials continue to develop, increasing the number of ion-selective electrode, has reached dozens of species. So in the past some dedicated ion meter such as pH meter and pNa meter can not meet the needs of most ion selective electrode measurements. The new requirements for measuring instruments for ion-selective electrodes are thus that they must be common to most ion-selective electrodes: the input impedance and the input current of the measuring instrument, the measuring range, the measuring accuracy, the correction of the electrode coefficients Regulator Fan
