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.

Implementing a peptide screening SPE plate determines the appropriate choice for a wide range of chemically diverse peptides.

The optimized dual solid phase extraction (SPE) method was developed to significantly reduce the surfactant background from formulated drug products.
