Essential Oils GC/MS

Batch Number: YO217

Ylang Ylang is always a bit different to the others in that it rarely fits neatly into the ‘standard spec’ ratio of the components. We always test the sample first and then decide whether we want to proceed with the order from the same batch. The main things we look for with Ylang Ylang testing are:
1. That each of the main chemical components that are supposed to be present are all present (they are)
2. That there are no signs of adulteration (there aren’t)
3. The scent… it’s amazing from this batch if we do say so ourselves 🙂

One thing to note is if you are looking for specific therapeutic properties from Ylang Ylang essential oil. If this is the case then you should take more notice of the chemical component ratio and make sure that the required components (that provide these properties) are present in high enough quantities.


What Is GC/MS Testing?

Gas Chromatography (GC)

Gas Chromatography (GC) describes the analytical separation technique used to analyze volatile substances in the gas phase. With GC, each chemical component passes through the gas chromatograph instrument at different speeds and times and as it does so, produces a ‘peak’ which can be tall or short. So GC tells you the ‘peak’ reading of each component but not what the component actually is.

Mass Spectrometry (MS)

Mass Spectrometry (MS) is what identifies the chemical components by separating ions by their unique mass as different molecules have different masses and this is how they are identified. The analyst can then read the results of the GCMS and identify each chemical component and the quantity of each that makes up the sample, expressed in a percentage.

What Is ISO & What Are The ISO Standards?

ISO is the International Organisation for Standardization and is a non-governmental worldwide federation of national standards bodies. Their mission is to promote the development of standardization across a wide range of products and services and their work results in ‘International Standards’. They are also the main recognised body for universally accepted standards of essential oils.

They basically provide specifications to use as a guide when looking at essential oil compositions. Important to note though is that the scent and therapeutic properties of the oil can still be outstanding even if it falls outside of the ISO specified ‘range’.

Sometimes, providing the oil is pure and not adulterated, it depends on what you are specifically looking for from the oil that dictates what compositions would best suit your needs as different levels of certain components will produce differences in therapeutic properties and scent. The problem is few companies make this data available to you so you can make an informed choice and have confidence in the quality of the product.

Essential oils are a bit like wine in that harvest time, country of origin, soil and climate conditions, part of plant used, distillation, transport and storage can affect the ratio of the chemical constituents. It’s generally accepted that as long as the ratio differs due to natural causes like these and not adulteration, then this is part and parcel of aromatherapy and to some extent what makes it so interesting and exciting as no two oils are the same.
