Chloride pseudotitration in wines by FIA with a Ag2S/Ag tubular electrode as detector

Abstract The determination of chloride in wines by potentiometric titration with silver cation in a nonsegmented flow system (FIA) using a tubular electrode of silver/silver sulfide detector is described. There was good agreement between the results obtained using the FIA titration and those obtained using the reference procedure. The methodology developed is adequate for the determination of chloride in various types of wines with chloride contents between 5 and 600 mg/liter, at sampling rates of 60 and 120 samples per hour.
