Identification and Quantification of Impurities in Wines by GC/MS

This report describes the analysis of extracted wine samples by a sequential full-scan/SIM acquisition on a GC-MS system consisting of a Thermo Scientific ISQ single-quadrupole mass spectrometer and a Thermo Scientific TRACE GC Ultra gas chromatograph. The results were compared to the sensitivity limits of human tasters. This method allows wine makers to obtain precise measurements on the organoleptic parameters that determine wine purity on site rather than having to send samples for expensive, external analysis.
