Applications of Polarisation Titrations

The following are examples of analytes and analytical data, pertaining to foods or pharmaceuticals only, that are determinable by amperometric and biamperometric titrations. 

Of these, water is perhaps by far the substance most determined in foods by biamperometric titration. The determination of water is perhaps worthy of a more complete coverage. The determination is based on the titrimetric procedure developed by Fischer [87] in 1935. His procedure involved the preparation of a titrating reagent consisting of a mixture of iodine, sulphur dioxide and pyridine in methanol. The titration reaction with water involves a two-stage reaction  

The following are some categories of determinable substances carbohydrates, fats, and high protein foods. The References section provides several additional applications (references 88-100) and suggested texts for use with section 8.5.
