Capillary electrophoresis introduced to the analysis of wine and spirits - Case Study
Capillary electrophoresis system Capel 105-M
LEC (Laboratoire Expertises et Conseils) laboratory
Wine and spirits
One of the leading spirit production control companies in France, LEC successfully uses capillary electrophoresis (CE) for the determination of various compounds in wine and spirits with CE system Capel-105M, and managed to replace some conventional techniques.
Founded in 1994, the LEC laboratory is internationally recognized for its analysis and technical expertise in the areas of barrel making and spirits. The company performs about 3 thousand analyses of wines, wine materials, and spirits per year and has COFRAC accreditation. Among the methods traditionally used in the laboratory were titration and enzymatic method for organic acids, HPLC for aromatic aldehydes, AAS for metals and cations in spirits, and others, each for a particular analysis. Many of these methods have disadvantages such as lower sensitivity, expensive reagents and consumables, and they are cost and time consuming compared to CE. The number of samples in the laboratory could reach hundreds per day only for the analysis of organic acids, which took a lot of time.
