The cannabis market is expanding exponentially in the United States. As state-wide legalization efforts increase, so also do demands for analytical testing methodologies. One of the main tests conducted on cannabis products is the analysis for terpenes. This research focused on implementation of accelerated solvent extraction (ASE), utilizing surrogate matrix matching, and evaluation of traditional vs. more modern sample introduction techniques for analyzing terpenes via gas chromatography–mass spectrometry (GC-MS). Introduction techniques included headspace syringe (HS syringe), HS-solid-phase microextraction Arrow (HS-SPME Arrow), direct immersion-SPME Arrow (DI-SPME Arrow), and liquid injection syringe (LI syringe). The LI syringe approach was deemed the most straightforward and robust method ... (Full article...)
