Analysis of Terpenes in Cannabis Using Headspace Solid-Phase Microextraction and GC–MS

Headspace SPME combined with GC–MS for the qualitative and quantitative analysis of terpenes in cannabis offers several advantages compared to other methods. It does not require the use of organic solvents, does not coextract matrix, and provides additional means of peak identification and purity using spectral data. It is also a nondestructive method.

Pesticide and Mycotoxin Analysis: Mastering the Complexity of the Cannabis Matrix

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.

The Benefits of ICP-MS for the Determination of Toxic and Nutritional Elements in the Cannabis Family of Flowering Plants

The wide dynamic range of ICP-MS allows it to be used for the simultaneous determination of parts-per-billion levels of heavy metals including lead, arsenic, cadmium, and mercury, together with high parts-per-million levels of nutritional elements, such as phosphorus, calcium, potassium, and magnesium.

Rapid Determination of 24 Synthetic and Natural Cannabinoids for LC–MS-MS Screening in Natural Products and Drug Inspection Applications

Other techniques for monitoring cannabinoids, such as GC–MS and LC–MS, are limited to screening known species and are therefore always one step behind the designer drug market-where new, previously unknown variations of analogs of cannabinoids are constantly being synthesized. The method presented here addresses this problem by providing accurate masses for all detected species, thus allowing postanalysis identification of initially untargeted compounds.
