Cannabis Potency by GC-FID with Carrier Gas Comparison (Helium, Hydrogen, Nitrogen)
Cannabis potency can be determined using a number of analytical techniques. In this application note we will describe a method using Gas Chromatography with a Flame Ionisation Detector (GC-FID). SCION also has application notes discussing other techniques such as HPLC (AN145) and GC-MS (AN142), these can be found on our website. Helium has been the standard carrier gas for GC applications however, due to recent global shortages many companies are keen to find alternatives.[3] This application note will give a comparison between different carrier gases showing the variation in results between the two alternatives to Helium; Hydrogen and Nitrogen.
Determination of Terpenes in Cannabis by GC-FID (using 8300 GC / 8500 GC)
June 14th 2024Hemp and marijuana are becoming more popular because of legalisation in multiple countries. The increase of this market also increases the offer of products and therefore the need to monitor different components. One of these components are cannabinoids or just short potency analysis, which can be found in our portfolio of Cannabis applications (AN091,92,93,130). This application focusses on terpenes analysis.
Cannabis Potency Analysis by HPLC (June 2024)
June 14th 2024CBDV, CBGA, THC-A and CBDA cannot be detected with FID or MS without extra sample preparation due to decarboxylation caused by the heat of the injector. The HPLC is a perfect instrument to measure these components since it does not use heat for the injection. Discover the advantage of this technique being able to analyse acidic cannabinoids without the lengthy sample preparation seen in GC methods.
