BigWigTrade is a producer, distributor and exporter of authentic, genuine and pure lavender essential oil made in Bulgaria.

A Certificate of Analysis is the result of testing against acceptable parameters. Certificates of Analysis can look quite different from product to product, industry to industry. However, with Essential Oils, measurement quite often consists of the dominant constituent of a particular oil.

GC stands for Gas Chromatograph. In simple terms, a GC separates an essential oil into individual components. The oil is vaporized upon entry into the device, and the oil passes through a column assisted by a carrier gas (usually helium or hydrogen). The column itself sits within an oven; here change in heat over time is managed. Different chemical compounds react at different speeds within the column, and this information is captured on the Gas Chromatograph. GC reports are unique, and in many publications, they are referred to as fingerprints of that particular batch of essential oil. They help purchasers protect their quality by ensuring major constituents are within generally accepted guidelines, as well as providing quantitative proof that received product matches approved samples. Still, it is important to note some of the limitations with GC's. While a GC may produce a unique fingerprint of an essential oil, this result is often unique to the GC device and the skill of the user. Even when conditions such as the type of column being used, ambient temperature, retention rates, etc are held equal, results may have slight variations. Another limitation is that without Mass Spectrometry (MS), a device significantly more expensive than even a GC, individual components cannot be identified.
