Fast Screening for Selected Doping Substances in Urine Samples using GC-TOFMS

In this note, a drug screening method for the determination of several beta-blockers and opiates in multiple urine samples is presented. The run time of the GC separation was less than 9 minutes. In parallel, other compounds not present in a target list but present in the sample can be identified by standard library search of the deconvoluted spectra.
