2:05 pm EDT (20:05 CEST - Praha) Comprehensive Analysis of Cannabis Using Two-Dimensional Gas Chromatography with High Performance Time-of-Flight Mass Spectrometry (GCxGC–TOF-MS)

David E. Alonso, PhD, Applications Chemist, LECO Corporation, St. Joseph, Michigan

Hemp characterization is not only important for determining its legality in the United States, but also critical for determining the effectiveness and safety of its many products. Regrettably, reported test results are often incomplete or inaccurate. In this study, gas chromatography–mass spectrometry (GC–MS) and comprehensive GCxGC–MS technology were used for untargeted analysis of cannabis botanicals. The methodology included pesticide analysis, potency determination, and terpene profiling. Data collection was comprehensive; however, both targeted and untargeted data processing methods were utilized for the quantitative and qualitative analysis of samples. The analytical methodology provided data with superior chromatographic resolution and increased peak signal to noise values, which dramatically improved compound detection and identification. Enhanced chromatographic plots and high-performance TOF-MS facilitated chemical classification and differentiation of cannabis samples.
