Analysis of Active Cannabis Compounds in Edible Food Products: Gummy Bears and Brownies

Potency testing in marijuana-infused edibles is a problematic task due to the complexity of the matrices. The concentration of active ingredients in edibles can range from a few ppm to 3.5% (1). In this application, active cannabinoid compounds were extracted from gummy bears (and also brownies, results not shown), followed by HPLC analysis.

Determination of Additives in Beverages Using Ascentis Express Columns

Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable.
