Development of a QuEChERS-based extraction method for the determination of destruxins in potato plants by UHPLC–MS/MS

Ultra high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) with electrospray ionization has been proposed for the determination of fifteen natural destruxins (A, B, C, D, E, Ed, Ed1, A2, B2, D2, E2, Cl, DesmA, DesmB, and DH-A), secondary metabolites with … Continue reading

On-line preconcentration strategy for the simultaneous quantification of three local anaesthetics in human urine using capillary zone electrophoresis

The simultaneous determination of usually employed anaesthetics (procaine, lidocaine and bupivacaine) has been developed and validated using capillary electrophoresis with ultraviolet detection at 212 nm. The separation of these three drugs has been achieved in less than 7 min, using … Continue reading
