Editors’ Series Exploring Chemical Constituents in Cannabis Using Nontargeted GC and GCxGC with TOFMS

Webcast

We know cannabis is complex, so where do we start. Nontargeted screening provides a wealth of information about the chemical constituents that are found in cannabis samples. This presentation demonstrates technology that takes us one step closer to answering “what’s all in there?”.

Event Overview:

Cannabis is difficult to analyze because of its chemical diversity, but more importantly the wide concentration ranges of its constituents. This chemical diversity can be very important in determining its utility, potency and medicinal effectiveness. A powerful, nontargeted discovery technique-gas chromatography- and two-dimensional gas chromatography paired with time-of-flight mass spectrometry-was used to determine a wide range of constituents including cannabinoids, terpenes, terpenoids, noncannabinoid phenols, nitrogenous compounds, flavonoids, and contaminants such as residual solvents and pesticides.

Key Learning Objectives:

Introduction to two-dimensional gas chromatography (GC x GC) and time-of-flight mass spectrometry (TOFMS)

Nontargeted screening data analysis schemes

Various components and compounds classes found in cannabis samples
