Detection of carrier oil adulteration in essential oils by GC-FID

Essential oils are complex mixtures of aromatic plant-derived compounds and an important tool in natural medicine and everyday health and well-being. However, the price premium of essential oils makes them particularly sensitive to economically driven adulteration. This poster, presented at the SelectScience^® Virtual Analytical Science Summit 2022, describes the development of a repeatable limit method for the detection of carrier oils in essential oils using gas chromatography with flame ionization detection (GC-FID).
