Gas chromatography can identify oils that have been processed, reconstituted, rectified or in other ways chemically manipulated. It also shows the variation in the natural chemical constituents - an important factor in determining the therapeutic quality of the oils.   The best GC  detectors are still inferior to the discriminatory ability and sensitivity of the trained human nose. 

The chiral capillary column can distinguish between so called "nature-identical" (man-made) aromatic compounds and botanical (plant-made) compounds. A true "nature-identical" compound has the same structure as a natural plant compound, however, it differs in a characteristic of the molecules called handedness. In the man-made compound the ratio of left-handed molecules to right-handed molecules (one being the mirror image of the other) is 50:50, whereas plants usually produce one or the other in higher numbers. The handedness of the aromatic plant molecules is specific to their physiological effect.

The vast majority of essential oils produced worldwide are for the flavor, fragrance and toiletry industry - an industry which does not need a botanically pure product but rather a consistent and reasonable priced product.

The ability to identify true whole natural oils is therefore critical to anyone who wants to experience the therapeutic benefits.

Gas chromatography testing services are available to the general population for $150 per essential oil and to wholesale customers for $10 per essential oil.  A summary report accompanies the GC readout.

The certification course is divided into 4 levels, totaling 5-6 days (not successive) of course/lab work. Certification is given upon completion and presentation of a research paper.
