Urine and plasma specimens fortified with 82 drugs and metabolites were prepared and analyzed by liquid chromatography quadrupole time-of-flight mass spectrometry (QTOF) instrumentation from three different vendors using the instrument manufacturers' methods and workflows for drug screening. No prior knowledge about the compounds included or their concentrations were provided. Samples were prepared and sent for analysis on a TripleTOF(®) 5600 system, a 6530 QTOF and a Xevo(®) G2-S QTof. All three platforms performed well with >90% of compounds detected in one set of spiked plasma samples, and 79-88% for a second set of spiked plasma and two sets of spiked urine samples.
