Characterization of Beverage Products Containing Cannabidiol (CBD) by GCxGC-MS Analysis
Cannabidiol (CBD) and products containing CBD have grown in popularity in recent years. In this 30-minute presentation, we aimed to characterize the chemical composition of CBD infused beverages by performing both targeted and non-targeted analyses in a single analysis that combined HS-SPME, GCxGC, and TOFMS.

Editors' Series: Exploring Chemical Constituents in Cannabis Using Nontargeted GC and GCxGC with TOFMS
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.
