1.This paper used 2m×?3mm glass column packed with 0.5% EGA on 80～100 mesh Gaschrom Q and isooctyl alcohol as the internal standard to separate allyl isothiocyanate and allyl thiocyanate .
2.Abstarct:Menthol and Eucalyptus oil in confection products were determined simultaneously by gas liquid chromatography,with columns packed with 10%carbowax (polyethyleneglycols) on 80/100 mesh diatomite with decanol as internal standard.
3.METHODS:Analysis was carried out on a 3 m×3 mm ID. vycor gas column, coated with DEGS, 10% spreading concentration, column temperature at 185℃. The linoleic acid was quantified by external standard method.
