Our labratory analysis is led by our chemist Dr. Anthony Ferrari and our lab technician Mikella Zgliczynska. Each oil goes through 6 major analysis techniques. Together, these techniques can identify any possible adulterations of the oils. Using organoleptic analysis, we also ensure that the aroma quality of all oils meets the highest standards. It is this marriage of science and superior aromatic quality that creates the best oils in the industry.

How to Read a Certificate of Analysis

1.) Identifying the product name, genus and species of the plant (Latin name), LOT number for the product in question:

The Latin name describes first the genus of the plant, followed by the species of the plant. In this specific example, "Lavandula" is the genus for Wild Lavender and "angustifolia" is the species of the plant. It is important to identify the Latin name with oils that have similar names, because either the genus or the species may vary, which could affect the chemical composition. The LOT number is our (Ananda's) method of tracking a batch of an oil the moment it enters our facility. Each LOT number is tied to only one Certificate of Analysis.


2.) The General Properties of the oil describe the plant part, the cultivation method, the extraction method, and the country of origin:

The plant part varies for different oils and can be telling to the properties or chemical components in the oil. The cultivation method can be wild, natural, or organically cultivated. The requirements for these are defined by the USDA and EU NOP standards.  We have been certified as an organic production facility and meet all the requirements from ECOCERT for every oil labeled and sold as “organic.” The extraction method will vary from “steam distillation,” “COextracted,” “solvent extracted,” and “cold pressed.” Each extraction method will target different constituents from the plant. The country of origin refers to where the plant material was grown and harvested, and not necessarily where the oil was distilled.


3.) The Technical Data are a set of fingerprint measurements that are used to identify any possible inconsistencies of the oils when compared to previous tests:

These values of specific gravity, refractive index, atomic rotation (or optical rotation) and viscosity are compared to a previous tests and literature values of specific oils. Click on the links to learn more about each of these “fingerprint” tests. The results of tests vary slightly between each oil, but remain within a certain range when no adulteration has occurred.


4.) The second page lists the Molecular Percentages and shows the composition of the oil by percentage:

The chemical composition will show which chemicals are present and at what abundance. This data is a key portion of the Certificate of Analysis and should be carefully examined when choosing an oil.


5.) The GC spectra shows the peaks associated with each chemical compound. The numbers above each peak are associated with the chemical compound listed in the Molecular Percentages table:
