Descripción

Analysis Note

Sample pretreatment: β-glucuronidase hydrolysis

The workflow for the LC/MS analysis of native drugs and associated metabolites from urine is shown here. The convenient liquid form of beta-glucuronidase from Sigma was used for hydrolysis of the glucuronide metabolites. SPE using Supel-Select HLB yielded clean extracts. The Ascentis Express F5 columns gave highly efficient, well-resolved peaks and rapid separation. Ultra high purity LC-MS solvents and additives provided trouble-free operation, and Cerilliant CRMs gave reliable quantification.
