描述了一种易于安装的小型化 Ag \ AgCl 参比电极。其电化学行为通过微极化曲线、电化学阻抗谱和瞬态电位得到证明。使用饱和氯化钾溶液，通过添加琼脂将其固化。电极直径小至800μm，长度5mm，具有进一步小型化的潜力。修改后的版本在同一毛细管中包括琼脂盐桥。 6 小时诱导期后，电位稳定在 1 mV 范围内，持续时间超过 6 周。电极显示出略有不同的参考电位，这是在生产过程中讨论的。 (C) 1999 Elsevier Science S.A. 保留所有权利。
A miniaturised Ag \ AgCl reference electrode is described which can be easily set up. Its elechochemical behaviour was proven by micropolarisation curves, electrochemical impedance spectroscopy and potential transients. A saturated potassium chloride solution was used which was solidified by adding agar. The electrode is as small as 800 mu m in diameter and 5 mm in length, with further potential for down-sizing. A modified version includes an agar salt bridge in the same capillary. After an induction period of 6 h the potential becomes stable within 1 mV for more than 6 weeks. The electrode shows a slightly different reference potential, which is discussed in terms of the production process. (C) 1999 Elsevier Science S.A. All rights reserved.
