Multidimensional capillary GC-GC for the analysis of real complex samples. Part II. Enantiomeric distribution of monoterpene hydrocarbons and monoterpene alcohols of cold-pressed and distilled lime oils

The enantiomeric distribution of sabinene, β-pinene, limonene, linalool, terpinen-4-ol, and α-terpineol for cold-pressed Key lime oils type A and type B, cold-pressed Persian lime oils, and distilled lime oils has been determined by a fully automated, multidimensional, double-oven (GC–GC) system using a SE-52 precolumn and a β-cyclodextrin main column. This system allows fractions to be multransferred during the same GC analysis and the use of the two GCs independently when the multitransfer option is not used. The results allow us to distinguish cold-pressed Key lime oils type A and type B, cold-pressed Persian lime oils, and distilled lime oils.
