Analysis of Anions, Organic Acids, and Cations in Wine by Capillary Zone Electrophoresis
17 Sept 2012In this application note the practical application of capillary electrophoresis technology for the analysis of ions in various commercial wine samples is demonstrated. The generation of anion, organic acid, and cation profiles is focused on and the simplicity of the technique as well as its capability to perform high resolution separations quickly and reproducibly is illustrated.

Capillary ElectrophoresisCapillary electrophoresis (CE) is used to separate molecules based on charge, size and hydrophobicity. Pressure, voltage or a vacuum is used to introduce the sample to fused silica capillaries. Fluorescence, UV/Vis, UV or diode array detectors are used to visualize components. Types of CE systems include capillary electrochromatography (CEC), capillary zone electrophoresis and capillary gel electrophoresis.

Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Quality ControlQuality control is needed in all production processes. Quality control is a monitoring procedure or set of procedures that are put in place to ensure that a manufactured product adheres to a defined set of quality criteria. Wine
