Bibliographic study of potentiometric methods of wine and must analysis

Abstract

In this paper, an overview of the application of potentiometry to wine and must analysis is presented. The large number of electrodes nowadays available with good characteristics for routine use, namely good selectivity and low response times, allowing measurements in a broad linear dependence range, with a relative low cost, simple sample pre-treatrnent requirements, no sensitivity to colour or turbidity of the samples, make potentiometry an attractive instrumental technique for wine and must analysis. Methods developed so far present good precision and the results show a fairly good agreement with those obtained by the application of reference methods.
