Poster Information
Abstract: Cannabis is a complex mixture: terpenes, cannabinoids, flavonoids, etc.
Medicinal uses include treatment of chronic pain, multiple sclerosis, epilepsy, anxiety, and cancer.
Its total composition is important in determining potency and medical effectiveness (Entourage Effect).
In this study, a novel analytical approach was utilized for the effective characterization of terpenes in different cannabis strains.

Investigative Objectives
Implement the use of enhanced, comprehensive two-dimensional gas chromatography (GCxGC) for the separation of cannabis terpenes.
Use a benchtop, high performance time-of-flight mass spectrometer and powerful processing software to quickly and confidently identify terpenes and other cannabis compounds.
Use software tools to compare different cannabis strains.
Summary: The Pegasus BT 4D facilitates fast and confident cannabis product “fingerprinting” through enhanced two-dimensional chromatographic resolution and high performance TOFMS.
Robust compound identification was achieved through spectral similarity searches of large, well-established databases, mass D determinations, and retention index filtering.
