描述了一种灵敏的电化学检测器，它使用 PTFE 粘合扩散电极来克服其他电化学检测器的主要局限性。该技术对 H2S 具有最大灵敏度（检测下限为 7·10−2g），其中每当量转移 8 个电子，对 NO、CO、SO2 和 NO2 的灵敏度较低。它坚固耐用，易于操作，可与多种载气一起使用。讨论了它在检测其他电化学活性气体中的用途。
A sensitive electrochemical detector is described which uses a PTFE-bonded diffusion electrode to overcome the major limitations of other electrochemical detectors. This technique was shown to have the maximum sensitivity for H2S (lower detectable limit of 7·10−2g) where eight electrons per equivalent are transferred and lower sensitivities for NO, CO, SO2and NO2. It is rugged, easy to operate, and can be used with a wide range of carrier gases. Its use for the detection of other electrochemically active gases is discussed.
