SUMMARY: Gas‐liquid chromatographic methods are described for the identification of 87 components in distilled alcoholic liquors. Water‐free concentrates of ether‐pentane or Freon extracts of the distillates were injected into different column systems and the column effluent transported to a mass spectrometer. To our knowledge, 34 of the identified compounds have not been reported previously in whiskey.

SUMMARY– A single‐pass gas‐liquid chromatography method is described for identifying compounds not reported previously in distilled alcoholic liquors. Water‐free concentrates of ether‐pentane extracts of the distillates were injected into a gas chromatographic column train and the column effluent transported to a mass spectrometer. Several hydrocarbons, and compounds apparently resulting from the reaction of acrolein with ethyl alcohol, were identified in the samples.
