Rapid Cannabinoid Testing Method for Cannabis Quality Control Using an Atmospheric Solids Analysis Probe Coupled with a Compact Mass Spectrometer (ASAP-CMS)


A simple, sensitive and selective ASAP sample introduction approach to measuring the presence of two isobaric compounds, CBDA and THCA, contained in a complex sample such as hemp or cannabis plants or their corresponding extraction products. Measurements are made of differences in the relative composition of CBDA and THCA fragment ions originating from the same precursor ion. Applicability to screening plants and plant product materials such as hemp or marijuana to monitor out-of-specification composition is demonstrated.
