Vaz Química milk Chloride potentiometry dairy products increased sensitive detector This paper describes the development of a flow injection analysis (FIA) system for the determination of chlorides in dairyproducts by potentiometric flow titration with increased sensitive detector. The potentiometric detection system used consisted of asilver ion-selective detector electrode based on a homogeneous crystalline double membrane and its potential difference was measuredagainst a common reference electrode by an external electronic device. Milk samples were straight injected into the automatic systemwhereas cheese, butter and yoghurt samples were prepared according to reference methods and the solution produced was insertedwithout further treatment. The results obtained for chloride determinations using FIA titration are in agreement with those providedby the reference methods (R.D. < 4%). The sampling rate accomplished with the automatic system varied from 130 to 250 samples perhour, depending on the samples chloride concentration. Ó 2000 Altaga.
