title: Gas chromatographic-mass spectrometric determination of ethyl carbamate in alcoholic beverages.
abstract: A sensitive and specific method based on gas chromatography-mass spectrometry for the quantitative determination of ethyl carbamate in table wines, fortified wines (such as ports and sherries), distilled spirits, brandies and liqueurs has been developed. Three characteristic ions from ethyl carbamate [m/z 89 (molecular ion), 74 and 62] were monitored in the selected-ion monitoring (SIM) mode. The lowest detection limit (based on the response on the m/z 62 ion) was estimated to be 0.5 ng/g (ppb). Additional confirmation techniques, including high-resolution SIM, and methane or isobutane chemical ionization are described.
