Identity & Purity Testing

Because identity and purity are key attributes of any essential oil, testing for these attributes is the best way to assure an oil’s quality. At NOW® Solutions our identity and purity testing program consists of four individual tests:

  • Gas chromatography
  • Infrared spectroscopy
  • Refractive index
  • Specific gravity

The combination of these four individual tests, and the ability to perform these sophisticated tests in-house and on-demand, provides NOW Solutions and our customers with powerful assurance of the identity and purity of our essential oils. These tests are performed on all of our essential oils.

What’s on the label is what’s in the bottle

At NOW® Solutions we take assurance of the quality and purity of our essential oils very seriously. We’ve made long-term investments in the instrumentation and the professional staff necessary to assure the identity, purity and quality of our essential oils, and we work closely with our growers and suppliers to assure the quality of our raw materials.
