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.
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.We evaluated a modified QuEChERS LC-MS/MS method for analysis of multiresidue pesticides.
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.
The method presented here allows for the accurate, precise, and robust speciation, profiling, and quantification of cannabinoids in hemp oil extracts and commercial cannabinoid products for research and development laboratories.
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 transition of cannabis from an illegal drug to a drug for medical and even recreational use raises challenging questions for regulatory agencies and analytical chemists alike. Here, we show a selection of analytical techniques based on compact mass spectrometry in combination with three different sample inlets (atmospheric solids analysis probe), thin-layer chromatography, as well as classical liquid chromatography) for the detection and quantification of cannabinoids and pesticides in cannabis-related material and contraband.
