We report systematic screening of different native and derivatized, charged and uncharged cyclodextrin (CD) derivatives for chiral separation, by capillary electrophoresis, of the enantiomers of omeprazole and pantoprazole, the two most frequently used proton-pump inhibitors. To optimize the analytical and electrophoretic conditions the effect of buffer composition, concentration, and pH, chiral selector...
A novel appro ach for the determination of ciprofloxacin, norfloxacin and ofloxacin by capillary electrophoresis and off-line capillary electrophoresis–matrix-assisted laser desorption/ionization-time of flight-mass spectrometry coupling for the confirmation of analyte identities is presented. A polymer capillary coating was proposed with the aim to minimize suppression of the MS signal caused by...
