该机是一种微处理机控制的全自动分析仪器，其测量部分包括一个玻璃的钠离子电极、一个在PVC片由之撷氨霉素的钾离子电极和一个双接头参比电极。在测量中，采用A、B两种标准溶液进行两点标定，求得电极的斜事，再通过比较测量法测出样品中K”、Na“的含量。一般地，根据仪器使? The machine is a microprocessor-controlled automatic analytical instrument. The measurement part includes a glass sodium ion electrode, a potassium ion electrode of the valinomycin contained in the PVC sheet, and a dual-joint reference electrode. In the measurement, two standard solutions of A and B were used for two-point calibration, and the electrode was evaluated obliquely. The contents of K and Na in the sample were measured by comparative measurement. Generally, according to the instrument?
