Besides the tests and determinations already indicated among the general methods (the tasting, determination of the specific gravity and the tests relating to volatile impurities and to denaturants, are made on the distillate, freed if necessary from essential oils), analysis of liqueurs includes the following.

A monograph on the chemotaxonomy of flowering plants extensively lists plant products and their occurrence by broad chemical type 68 however, lists are not complete, as of 1969, and detailed references are not usually given. A classic lexicon of fragrant materials has been completely revised,69 a review of essential oil analysis covering the period September 1972 to August 1974 has been published,70 and volatile leaf oil analysis in chemosystematic studies has been reviewed.71... 

The FID in conjunction with high efficiency capillary columns has found wide application in the analysis of hydrocarbons. It is also employed extensively for pharmaceutical analysis, pesticide analysis, forensic chemistry and essential oil analysis, but its major area of application is in the analytical laboratories of the hydrocarbon industry. 

The combination of GC with olfactometry is another possibility for detection that has been used in essential oil analysis. Olfactometry adapters are commercially available and should include humidity of the GC effluent at the nose adapter and provide auxiliary gas flow. The correlation among eluted peaks with specific odors allows accurate retention indices or retention times to be... 

The application of multidimensional gas chromatography (MDGC) to essential oil analysis is a great development in the determination of such complex samples. This is an appropriate approach when there are zones on the chromatogram where the peaks are not well resolved, which is a common situation in natural samples. The fractions corresponding to the zones with unresolved peaks are transferred to a second column containing a different stationary phase, where they are separated and completely resolved. Therefore MDGC permits the separation of poorly resolved peaks and increases resolution, with the final result of an improvement in both identification and quantification of components of essential oils.
