ABSTRACT:
A gas-liquid analyzer comprises a sample conveying assembly having a capillary tube with a sample under analysis, the walls of the tube being provided with two rows of openings arranged in opposition to each other. The openings of one of the rows accommodate hermetically secured ion-selective electrodes connected to a switching unit wired with a potentiometer and a potential corrector. Secured in the openings of another row are porous inserts adapted to contact electrolyte. The presence of sample under analysis between the porous insert and the ion-selective electrode causes the latter to come into contact with a reference electrode electrically connected to the potentiometer.
