Quality and Chemistry

The Quality of an oil is gauged from therapeutic viability and aroma profile (organoleptic properties). We check all of our products using GC/MS testing. This technique is described further in our "GC/MS Explained" section, but to sum it up, we match our spectra to a database which will identify compounds in a complex mixture (like an essential oil). These identifications are based upon a fragmentation pattern that is unique for each compound in our library. Each oil that can be tested via GC/MS is done so without ever contaminating our oils, because of the sample size required to do GC/MS testing (approximately 1 drop of oil).

We make sure all of our oils have the correct chemical constituents at reasonable ranges when compared to other GC/MS reports. We also use fingerprint tests such as: refractive index, optical rotation, specific gravity, and viscosity. These fingerprint tests can quickly indicate that an oil may have adulteration. At EOW we have a passion for high quality, and this passion is directly met with a high understanding of chemical components in each of our products. While we understand the importance of chemical results from a testing stand point, we do understand that the chemical analysis does not directly lead to quality, it is just a part of the overall aspects that define quality for our oils here at EOW.
