众所周知,离子选择电极是根据能斯特公式求出待测离子活度的一类电化学传感器。它具有选择性、灵敏度高、响应快及测量范围宽等特点,已广泛用于工业、化学、医学、食品、地质、土壤、环保、过程监测和在线监测等方面,尤其是与计算机联用,可提高数据处理能力,若配上流动注射分析,可大大提高分析速度和精度。离子选择电极分玻璃膜、固膜、液膜、修饰电极、酶电极、涂丝电极、ISFET 电极
It is well-known that an ion-selective electrode is a type of electrochemical sensor based on the Nernstian formula for determining the ion activity to be measured. It is widely used in industrial, chemical, medical, food, geology, soil, environmental protection, process monitoring and on-line monitoring, especially in combination with computers. It has the advantages of selectivity, high sensitivity, fast response and wide measuring range. Can improve data processing capabilities, coupled with flow injection analysis, can greatly improve the analysis speed and accuracy. Ion selective electrode sub-glass membrane, solid film, liquid film, modified electrode, enzyme electrode, coated wire electrode, ISFET electrode
