Abstract:
The bonded phases generated from the reaction of aliphatic and aromatic azidosilanes with silica gel are suitable for use as packings in solid phase extraction columns for cleanup of urine samples for analysis of acid metabolites of cannabinoids. Such bonded phases are unique in their ability to selectively retain the acid metabolites of cannabinoids from a urine sample matrix.
