Indicator Techniques in Coulometric Titrations

A great many methods involving the determination of metals and inorganic analytes exist. These can often be apphed in food analysis, although the techniques of voltammetry/polarography, atomic absorption, ICP, etc., have in 

In many apphcations, particularly those involving the determination of metals in food substances, there is a necessity of wet- or dry-ashing the sample prior to analysis in order to remove possible interferences.
