This compendium explores how mass spectrometry can interrogate cannabis in record time, detecting heavy metals, pesticides and residual solvents – all highly harmful to consumers in substantial amounts. In terms of desirable compounds, modified mass spectrometry techniques can also be harnessed to detect and catalog cannabinoids in a matter of minutes.Along with methods of terpene detection and deep-dive features on decarboxylation, this collection is a must-read for anyone interested in the growing scientific field of cannabis testing.
