A gas and liquid analyser comprises a component (21) for feeding in a sample to be analysed, which component has a capillary tube (4), which contains a sample (6) to be analysed and in whose wall two rows of orifices are formed opposite one another. In the orifices of one of the rows, ion-selective electrodes (11, 12) are arranged hermetically, which are connected to a switching unit (13) which is connected to a potentiometer (14) and a potential correction unit (15). Incorporated into the orifices of the other row are porous inserts (7, 8) which come into contact with an electrolyte (3). At the time when the sample (6) to be analysed is present between the porous insert (7, 8) and the ion-selective electrode (11, 12), the latter is in contact with the reference electrode (1), which is connected to the potentiometer (14). …<IMAGE>… |
