Spectroscopic Determination of Methanol Content in Alcoholic Drinks

Popis výsledku v původním jazyce

The aim of this paper is to introduce an innovative method for measuring the concentration of methanol in alcoholic beverages. The novel approach consists in using Raman spectroscopic data for methanol content detection. Raman spectroscopy is a powerfulmethod for material identification giving information about the structure of examined sample. This analytical method enables rapid, noncontact and non-destructive analysis that can be performed through the glass. The method for quantitative determinationof methanol in alcoholic beverages has been developed on the basis of diverse Raman spectra for methanol and ethanol, their mathematical processing and using PLS regression method for the calibration and prediction model of methanol. Development of thisnew method is related to the massive methanol poisonings which occurred in the Czech Republic in September 2012. A large amount of harmful toxic alcoholic drinks containing methanol in quantities many times over legal limit was illegally
