Assessment of Methanol Content in Alcoholic Drinks Based on Raman Spectra

Popis výsledku v původním jazyce

This contribution presents the development of method for quantitative determination of methanol in alcoholic drinks 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 this procedure 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 distributed. This event led up to serious problems with poisoned people and the losses in lives. However, it can be assumed the problems may occur in the future since about a third of the defective alcohol hasnot been traced. Raman spectroscopy offers advantages over other methods namely rapid, noncontact and non-destructive analysis that can be performed through the glass. The detection limit of the method lies below the permitted and safe a
