Essential oil purity

Essential oil purity

Analyzing purity and composition of essential oils

Essential oils contain many different compounds and almost all of them are optically active. SCHMIDT + HAENSCH polarimeters and refractometers are able to detect any change in the composition of essential oils by measuring the refractive index. A consistent quality can also be ensured by measuring the specific gravity using the SCHMIDT + HAENSCH VariDens. The density of the oil is measured in comparison to water. Each oil has a known range of specific gravity in which the oil is considered pure.
