Clark-like Hydrogen DetectorA quantitative hydrogen detector, similar to the Clark oxygen electrode, has been proposed by Green et al. [1] in 1967. Such a detector gives a signal which is directly proportional to the hydrogen partial pressure without consuming any hydrogen itself. We have taken up the proposal of Green et al., and have realized a very sensitive and under many circumstances also a selective detector, which is easy to handle and which can be used in gaseous phase as well as in aqueous solution. Sensitivity of 0.1 Torr or even better can be achieved. The main differences to the Clark electrode are that a platinized platinum electrode has to be used instead of a blank platinum electrode and that a more positive potential has to be applied. We give a detailed description of the construction and the handling of the Clark-like hydrogen detector.
