As an aromatherapist and a supplier of essential oils, I have learned that GC/MS reports are invaluable.
Pure essential oils are not just preferred but mandatory to achieve the therapeutic effect I might be looking for. Adulterated oils or perfume oils will not offer therapeutic effects and may in fact cause allergies, headaches and chemical sensitivities.
Gas Chromatography (GC) is a method of separating the volatile compounds in essential oils into individual components and produces a linear graph that charts these components. Mass Spectrometry (MS) identifies each of these components and their percentages. This process is used to identify any adulteration of the essential oil tested.
The precise breakdown of the chemical components in individual oils given to us by GC/MS reports are important as the therapeutic benefits and safety issues of essential oils are, in large part, determined by their chemical makeup.
Once an essential oil is tested, we format the chemical constituents into chemical families for therapeutic blending purposes. All the main components and some of the trace components will be listed on these reports. The chemical family information on Aromatics International is written for the oils sold on this website and is specific for each batch of oil we buy. You can see each essential oil’s GC/MS report by going to the essential oil’s page and clicking on GC/MS report.
As suppliers of essential oils we are dedicated to knowing exactly what we are buying and selling. Testing every batch of oil we purchase with GC/MS technology assures purity and gives us the exact chemistry of each oil. We believe this process is vital for medicinal blending and for quality assurance.
Over the past 15 years we have developed close relationships with our distillers. We test to learn the exact chemical make up of the oils, as there are many therapeutic properties associated with the individual components. We recently received a new oil that we were excited about. When the GC/MS report came back, it was obvious that it was adulterated. We were very surprised, as the last time we received an adulterated oil from one of our distillers was in 1998! We rejected the oil, sent the GC/MS report to the distiller and asked him about the oil. He had bought the oil from another farmer and offered it to his clients without testing it. This incident upset our distiller and he initiated a tighter control on the oils he buys from other farmers. GC/MS testing for every oil, batch specific, helped us immediately identify an unexpected adulteration.
Not all GC/MS machines are created equal. We use a chemist in France who has state of the art equipment and is able to identify 100% of the chemicals in our oils.
Take the guess work out of the quality of your essential oils and look for the GC/MS reports. Essential oils are a gift that we treasure.
