A novel SFC–QTOF-MS method accurately detected 10 drugs in oral fluid, matching LC–MS/MS in 83 DUID cases while reducing run time by 42% and organic solvent use by 81%.

The main objectives of this study were to develop a method for the measurement of cocaine derivatives in oral fluid by coupling a probe electrospray ionization (PESI) source with quadrupole time-of-flight (QTOF). The three cocaine derivatives considered were: benzoylecgonine (BZE), cocaine, and ecgonine-methylester (EME).

How can low-resolution mass spectrometry (LRMS) and high-resolution (HR) MS work together to provide unambiguous results in clinical and forensic toxicology?

In this study, a probe electrospray ionization coupled to mass spectrometry (PESI-MS) method for ultra-rapid determination of MtF in plasma by isotope dilution was developed.
