Precise measurements are vital to any transaction of commerce. As the medical marijuana industry grows in the United States, in addition to standard weights and monetary measures, potency, impurities, and related measures become important.
The method described here allows for the simultaneous analysis of 47 pesticides and five mycotoxins in cannabis in one simple QuEChERS procedure. This simple method is designed for implementation in start-up laboratories and in established laboratories that wish to streamline their sample preparation process, decrease solvent usage, and obtain accurate and fast results.
Well-established techniques used by the food safety industry, such as QuEChERS sample preparation followed by LC–MS/MS for the analysis of multiresidue pesticides, are evaluated for use with cannabis plant material.
