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.

A single gas-liquid chromatographic column is described which will separate all the major fusel oil components rapidly and directly without prior concentration or extraction procedures. Quantitative data obtained using a 1:1 2% 1,2,6-hexanetrio 1:2% glycerol column compare favorably with those of the official AOAC colorimetric fusel oil method. Four additional components may be determined simultaneously and quantitatively.
