摘要: Abstract High concentrations of alcohol increase the difficulties in identifying different alcoholic beverages with sensor arrays, because odour-relevant species usually occur at much lower concentrations. In this study, characterisation beer brands was possible a modular system (MOSES II). The latter combined gas-chromatographic column thus enabling preseparation. classification independent ethanol content. Fermentation by-products could also be detected and classified. addition, types white wine one red were investigated by same method.
