A Quick Template for Technical Sheets
Alexis St-Gelais, Ph. D., chimiste – Popularization We are regularly contacted by natural extracts producers for assistance with technical sheet (TS) preparation, especially for the European territory. We can understand the reflex of contacting a laboratory to have this kind of document prepared, but the truth is YOU are in the best position to do […]
Terpene Groups as Strain Characteristics
Alexis St-Gelais, chimiste – Popularization & Plant profiles The intensive breeding of cannabis produces strains that have different molecular signatures, and this is quite apparent within terpenes profile. These features can be useful to characterize a strain or extract, by putting forward what sets it apart from another variety. Based on our extensive experience with […]
Terpenes & volatiles analysis: Theory and Applications
Alexis St-Gelais, chimiste – Popularization One of PhytoChemia’s most renowned assays in Canada is our detailed cannabis terpenes analysis. This assay can have different applications and comes in two declinations, “main” and “full” terpenes. Let’s have a tour on the ins and outs of our analytical service, and how it can be of use to […]
Heavy metals in cosmetics: Canadian guidance
Alexis St-Gelais, chimiste & Patrice Rondeau, technicien – Popularization Do you manufacture cosmetic products to be sold in Canada? If so, you should comply with Canadian guidelines for heavy metal impurities in such products, for which PhytoChemia can assist you efficiently. Even if you are in other businesses that use plant-sourced ingredients, our heavy metals […]
Optical rotation: application to oils analysis
Alexis St-Gelais, chimiste & Cindy Caron, chimiste – Popularization Have you ever heard of the term optical rotation or seen it on a certificate of analysis, and wondered what was its purpose? If the answer is yes, you are in the right place to learn more about its use and meaning. In this post, we will […]
Selina-4,7(11)-diene in Cannabis Terpenes, or How to Identify an Unknown Compound
Alexis St-Gelais, chimiste – Popularization Today, we want to give you a glimpse of the process involved when we are able to identify compounds that we earlier reported as unknowns in our gas chromatographic profiles, applying it to the case of cannabis terpenes. How can a Compound Noted as Unknown in GC Profiles Finally be […]
Pre-Treatments for GC-FID / MS Analyzes – The Example of Hydrosols
Hydrosol obtained with Explorer (an Alchemia Solution Still) Corine Lormel, PhD Samples often contain very different molecules. In analytical laboratories, finding the instrument which will identify and quantify them is the first step. For this purpose, the chemist must ensure that the chosen method can “separate” the compounds of interest but also makes them “visible” […]
