| refractive index |
Refractive index testing is one of four objective testing procedures Frontier uses to determine the quality of every essential oil. A refractometer is used to measure the velocity of a light ray passing through an essential oil. (Light behaves differently depending upon the density of the material it is passing through.) The reading is compared to established literature; deviations are indicative of adulteration.
