涂丝运算放大器小型氯电极的研制及应用

Preparation and Applications of a Miniature Selective Electrode with Operation Amplifier.

将对氯离子敏感的PVC膜直接涂在运算放大器的输入端,研制成功了涂丝运算放大器小型氯电报,并应用于血清中氯的测定。

A miniature chloride-selective electrode has been prepared with an operation amplifer as impedance transformator, while the membrane is directly coated on to the input stage of operation amplifier. The electrode is prepared easily and has good stability and fast response. The potential of membrane of the electrode can be measured by low impedance instrument and the electrode has been used successfully for determination chloride in serum.
