Ethyl Carbamate Analysis in Fermented Products: A Comparison of Measurements of Mass Spectrometry, Thermal Energy Analyser, and Hall Electrolytic Conductivity Detector

4. References > 1000 jAg/L. Typically, the concentration is low in wine and high in some spirits; the concentration is particularly high in some plum brandies but is low in gin and vodka. Literature methods [1,2,31 rely on sample clean-up followed by packedcolumn GC and detection by FID, alkali flame ionisation, electron capture, or Coulson electrolytic conductivity detector and allow measurements down to 10 Itg/L. The clean-up procedure required for levels below 100 jg/L is extensive and MS confirmation is still required. I.5 I~a 21 In the course of a study of ethyl carbamate levels in alcoholic beverages on sale in U.K., different methods of separation and measurement were as-
