The initial and long-term drift of tcPO2 microcathode electrodes has been shown to be substantially less when chloride is removed from the electrolyte, despite the probability that reference electrode EMF is less well defined. In addition to virtually eliminating drift, these electrolytes eliminate silver deposition on the cathode. The most successful electrolyte tested thus far has been 0.2 M K2B4O7 in 95% ethylene glycol, 5% water, both with and without cellophane spacers. The buffering produced by borate appears to prevent the downward drift in CO2 free air probably caused by Ag2 CO3 formation on the anode, after exposure to skin.
已表明，当从电解质中去除氯化物时，tcPO2微阴极电极的初始漂移和长期漂移会显著减少，尽管参比电极的电动势可能定义得不太准确。除了几乎消除漂移外，这些电解质还能消除阴极上的银沉积。迄今为止测试最成功的电解质是95%乙二醇和5%水的混合溶液中含0.2M K2B4O7，有无玻璃纸垫片均可。硼酸盐产生的缓冲作用似乎能防止在接触皮肤后，可能因阳极上形成碳酸银而导致的在无二氧化碳空气中的向下漂移。
