Microwave-assisted Acid Digestion of Cannabis Products with Pressure-activate Venting

Due to the legalization of cannabis and the associated legislation concerning trace metal analysis the demand for fast and easy-to-use acid digestion techniques is increasing. HVT vessels with SMART VENT Technology enable the convenient and reliable digestion of cannabis-based products prior to spectroscopic analysis.


Although prohibited in the early 20th century, cannabis is now undergoing resurgence in medical and recreational use. In recent years more and more countries legalized the use of medical marijuana and Uruguay, Canada, Georgia and some US states also legalized recreational use of cannabis. Compared to the well-established system of cultivation, processing and sales of cannabis products, the governmental regulations of quality control are far behind. There is a lack of standardized methods and each state is currently responsible for regulating the quality controls, leading to multiple different legal situations. However, to ensure consumer safety and product quality cannabis-based products and the plant material itself must be tested for the potency of active ingredients, the presence of pesticides and toxic heavy metals like arsenic, cadmium, mercury and lead. These metals are of special interest as they are hazardous to humans even at low concentrations.
