Use of Gas Chromatography for the Analysis of Cannabinoids and Terpenes

Webinar Abstract:
With the legalization process currently taking place in the US, finding new techniques for the fast, cheap, and comprehensive analysis of Cannabis sativa components has become a major point of interest. Different analytical tools have been widely used for the characterization of the main components of the plant, cannabinoids and terpenes. Both these classes of compounds can be analyzed with the use of the gas chromatograph coupled with the mass spectrometer (GC-MS), and with the vacuum ultraviolet detector (GC-VUV).
In this research, we used these two technologies to analyze cannabinoids and terpenes found in C. sativa; the sensitivity of the multiple reaction monitoring (MRM) mode used in the GC-MS allowed for the analysis of impurities, while the GC-VUV was more adapt for a potency testing. Terpenes were analyzed on GC-VUV due to the possibility of the instrument to differentiate between isobaric compounds, and to deconvolve coeluting peaks that otherwise would need a longer chromatographic separation.

Learning Objectives:
1. Why GC is a necessary tool for R&D and QC labs in the Cannabis world.
2. How new technologies are advancing to give a more comprehensive understanding of the plant.

    5:30 well that’s kinda true. actually a little bit thc might help increase the effect of cbd so that might be beneficial for some people . but ofcourse if you don’t want or can have thc then ofcourse only take cbd
