Sample Preparation and Trace Elemental Analysis of Cannabis and Cannabis Products
Introduction
As more and more cannabis and hemp based products make their way to market, cannabis testing labs are faced with the challenge of testing a wide variety of samples for heavy metals, and other contaminants, in a short amount of time. To improve throughput and productivity, digesting all samples in a single batch is preferred.
In this study a variety of cannabis product samples were digested in a single batch for heavy metals analysis by ICP-OES. These samples varied in composition and appearance but were digested in a single batch. Pre-digestion sample handling techniques for optimal digestion were also utilized.
