Method to detect heavy metals in cannabis approved

CEM Corporation's analytical method "Heavy Metals in a Variety of Cannabis and Cannabis-Derived Products," used for the analysis of toxic metals in cannabis and cannabis-containing products, has received approval from AOAC INTERNATIONAL.

This method uses high throughput microwave digestion and inductively coupled plasma mass spectrometry (ICP-MS) to solubilize and analyze arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), and other elements in cannabis products, including edibles, health and beauty products, and cannabis or hemp supplements. 

The new method was reviewed by a panel of analytical science experts and is the first method approved by AOAC for heavy metals in cannabis. The accuracy and precision of the ICP-MS-based method met the AOAC Standard Method Performance Requirements for Determination of Heavy Metals in a Variety of Cannabis and Cannabis-Derived Products) for all elements of interest.

"The method was developed to help cannabis labs determine total heavy metal content in their cannabis samples with simple and high throughput sample digestion and analysis instrumentation," the CEM team stated.
