| Abstract | CGUM-1 is a certified reference material (CRM) consisting of gelatin-based edible soft chews that have been infused with cannabinoids extracted from cannabis. This CRM is designed for use in method development, validation, and quality control for the analysis of cannabinoid-infused edible soft chew products or related matrices. Each unit of CGUM-1 contains four soft chew edibles. Certified values for the mass fraction of cannabinoids in CGUM-1 have been established. |
