Performance Evaluation of a Thermal Desorption System for Detection of Basic Drugs in Forensic Samples by GC/MS


App Note 11/2006

Stir bar sorptive extraction (SBSE) is an innovative sample extraction technique that can be used to process blood, urine, and tissue samples for routine drug screening in the forensic toxicology laboratory. Case specimens containing drugs typically encountered in forensic samples were evaluated using SBSE and compared with a liquid/liquid extraction method followed by GC/MS analysis. This evaluation demonstrated that SBSE method worked equally as well as the routine extraction method for the detection of basic drugs in screening forensic samples.
