ABSTRACT:
The method is based on the gas which is to be examined being absorbed in a flowing liquid and then dissociated. The ions formed are detected with an ion-sensitive electrode. In order to obtain a high solubility and thus a high sensitivity, the absorption liquid together with the gas is continuously atomized, the liquid phase is subsequently separated off and is fed, in a continuous flow, through a measuring chain having an ion-sensitive electrode.
