Severinghaus原理

WebStow-Severinghaus 型电极为固态玻璃 pH 电极。 测量时，CO 2 通过皮肤和薄膜扩散到 pH 电极中并在其中溶解，形成能改变溶液 pH 值的碳酸，之后，经过测量并转换为经皮 CO 2 分压 (tc p CO 2 )。 Web8 Jun 2015 · The Severinghaus electrode is essentially a slightly modified glass electrode. The CO2 dissolved in the sample diffuses into the middle compartment of the electrode via a thin membrane. Once inside, the CO2 finds itself in an aqueous solution. For convenience, there may or may not be a bicarbonate solution added to this chamber. The reaction …
