Collision cross section (CCS) database: an additional measure to characterize steroids.
Ion mobility spectrometry enhances the performance characteristics of liquid chromatography–mass spectrometry workflows intended to steroid profiling by providing a new separation dimension and a novel characterization parameter, the so-called collision cross section (CCS). This work proposes the first CCS database … 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

Mass spectrometric and contactless conductivity detection approaches in the determination of muscle relaxants by capillary electrophoresis
Novel and rapid capillary electrophoresis-coupled tandem mass spectrometry (CE-MS/MS) and capillary electrophoresis with capacitively coupled contactless conductivity detection (CE-C4D) methods have been developed for the separation and determination of three neuromuscular blocking agents: pancuronium, vecuronium, and rocuronium. In both cases, … Continue reading

Dispersive liquid-liquid microextraction prior to field-amplified sample injection for the sensitive analysis of 3,4- methylenedioxymetamphetamine, phencyclidine and lysergic acid diethylamide by capillary electrophoresis in human urine
A novel capillary zone electrophoresis (CZE) with ultraviolet detection method has been developed and validated for the analysis of 3,4-methylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD) and phencyclidine (PCP) in human urine. The separation of these three analytes has been achieved … Continue reading

Advances in the determination of β-lactam antibiotics by liquid chromatography
β-lactam antibiotics have been the most widely used antimicrobial drugs for more than 80 years and still constitute the most important group of antibiotics. Their extensive use in veterinary medicine practices as growth promoters, and chemotherapeutic and/or prophylactic agents causes numerous … Continue reading
