LEC modified the strategy for analyzing metals in spirits in capillary electrophoresis
The corporate LEC, one of many main liquor management firms within the Cognac area, has managed to maneuver from atomic absorption spectrometry (AA) to capillary electrophoresis (CE) ) to investigate metals in spirits with the assistance of Capel-105M.
LEC thought of that Lumex Devices' CE methods have been probably the most economical, user-friendly and dependable answer for fixing analytical oenology duties due to its excessive degree of accuracy and flexibility in comparison with different strategies . Though atomic absorption spectrometry is probably the most generally used approach for the willpower of metals in wines, from late 2018, LEC switched from this method to capillary electrophoresis to quantify iron ( II) and copper. Capel-105M had important and important benefits over the AA spectrometer beforehand utilized by LEC: easy pattern preparation, quick and correct evaluation, no particular calibration required for every aspect. As well as, this swap has lowered upkeep prices for LEC because it has lowered the variety of devices used for its analyzes.
Capillary electrophoresis has been proven to be a robust and dependable approach for analyzing the variety of wine and brandy compounds. The CE Capel system presents many benefits for the evaluation of wine and spirits, together with brief evaluation occasions, low waste manufacturing, a really excessive degree of accuracy and a variety of merchandise. d & # 39; purposes.
LEC bought its first CE Capel-105M system in 2011 to find out quite a lot of compounds in wine and spirits, comparable to fragrant aldehydes in cognac and brandies and natural acids in viticultural supplies. The analytical protocols developed by Lumex Devices with the assistance of CE have benefits over different generally utilized strategies comparable to titration or enzymatic technique. One of the necessary of them is the willpower of a number of compounds in a single go. As well as, LEC analyzes natural acids, sugars (fructose, glucose and sucrose) in meals and drinks, in addition to inorganic cations in wine with the CE technique. At the moment, LEC makes use of two Capel-105M methods.
Based in 1994, the LEC laboratory is internationally acknowledged for its analyzes and technical experience within the fields of barrel manufacturing and spirits. The corporate carries out round three,000 wine and wine materials analyzes a yr and is accredited by COFRAC.
