CLEAN SCENTED PRODUCTS ONLY IN QUALIS NUTRI
For essential oils, purity starts at the source; the planting, harvesting, and extraction processes take place before an essential oil ever reaches a lab.
Yet, there is still the potential for adulteration and contamination to occur before an essential oil reaches the consumer. To ensure that not only are your oils pure, but of the highest quality available, testing, such as GCMS, is a critical and important process.
GCMS is the standard for essential oil quality testing, GCMS stands for chromatography or mass spectrometry. They are two separate analytical tests that work together to analyze and give you accurate data regarding the chemistry of your essential oils.
Not only are Qualis Nutri oils tested through an independent, third-party lab, but Qualis Nutri also makes its GC/MS results (known as chromatograms) available for batches of its single essential oils.
Quality testing is key to pure essential oils, ensuring that these oils are safe for you and your family.
The only way to check for purity is GC/MS, anyone who tells you differently is simply uneducated in this field, blotter test is never as accurate as GC/MS when it comes to checking the quality and purity of the essential oils.
Essential oils can be inspected using several techniques. Another most common method is gas-liquid chromatography (GLC).
A small amount of essential oil is injected into a very fine spiral flat column with temperature control in this device. The time it takes for each component to appear at the other end of the column (so-called retention time) depends on the size of the molecule. The amount released is logged and peaks on the track (proportional to the amount).
This is a comparative test, not a definitive test, as the retention times for known components have already been determined to be useful for analysis. Because each batch of oils has a different composition ratio, the measurements for each oil are kept as “standard.” This standard can be compared directly with the standards for various essential oils of the same plant.
This technique shows that the added adulterant has a retention time that is not apparent by the standard. However, it is possible to mix oils that are low in certain ingredients by simply removing them from another usually cheap essential oil and “correcting” the reading.
Synthetic replicas of the component may be used, or if high concentrations of the element are required, oils with a high proportion of terpenes, such as peppermint oil, may be removed.
Aromatherapists “concentrate” the active ingredients, so care must be taken with such oils. Alternatively, the ingredients can be fortified, as in the case of eucalyptus added to eucalyptus oil.
GLC, infrared, optical rotation, density, mass spectrometry (GCMS) (very expensive but excellent), solubility in alcohol, and ester content of all tests performed on the most common essential oils.
