EA-IRMS: 13C and Simultaneous 18O and 2H Isotope Analysis in Ethanol with Thermo Scientific Delta V Isotope Ratio Mass Spectrometers
Oliver Kracht (1), Andreas Hilkert (1) and Tünde Racz-Fazakas (2)
Isotopic analyses of foods have become a widespread tool to evaluate the quality, authenticity and origin of labeled products. According to the standard procedure, wines, alcoholic beverages and fermented fruit juices are distilled to gain ethanol. Ethanol can be analyzed for oxygen and carbon isotope composition by elemental analyzers coupled to isotope ratio MS. The analyses allow the quantification of exogenous sugar added during the fermentation to increase the alcohol grade of the wine. The control of spirit drinks is needed also for the detection of frauds, such as mislabeling regarding both ingredients and origin.
