Anyone who uses or formulates with essential oils will have come across the term 'GC/MS' or 'Gas Chromatography / Mass Spectrometry'. GC/MS is often said to be the gold standard in the chemical analysis of essential oils, with a GC/MS report being the unique 'fingerprint' of an essential oil. A GC/MS analysis identifies the various constituents in an essential oil and lists how much of each constituent is present as a percentage. A GC/MS test is crucial in verifying the authenticity and purity of an essential oil. A report can be compared with a published standard or international specification, such as those published by the ISO (International Organization for Standardization), to confirm if it passes set criteria.

All of Flo Aromatherapy's Essential Oils undergo stringent testing by our suppliers dedicated quality control team. They conduct third-party GC/MS testing, considered the industry gold standard, to ensure that we can objectively stand behind the purity, potency, and authenticity of our oils.
