Abstract
A method of and an apparatus for manufacturing a measuring cell comprising a tube having a first end capped by a membrane of an ion-selective material, comprising the steps of: providing a paste comprising all constituents of the ion-selective material; mounting the tube onto a stick with a tip such that the stick extends through the tube; dispensing an amount of the paste onto the tip; heating the first end of the tube and the dispensed paste to a temperature causing the dispensed paste to melt and the thus-produced melt to form a film covering the tip and an end surface of the first end of the tube; transforming the film into the membrane joined to the tube by cooling the first end of the tube and the film to a temperature below a melting point of the ion-selective material; and separating the thus-manufactured measuring cell from the stick.
