Abstract: The use of an absorption trap off-line two-dimensional gas chromatography (2-DGC) in conjunction with a mass spectrometer greatly improved the separation andidefitification of minor constituents of a complex mixture such as a natural essentialoil.The absorption trap device used as an interface of 2-DGC offered the advantageof convenient manipulation.
