The hyphenation of chiral capillary electrochromatography (CEC) with electrospray ionization mass spectrometry (ESI-MS) is very challenging but promising due to the fact that it combines sensitivity with high specificity and selectivity. In this work, CEC capillaries packed with (3R,4S)-Whelk-O1 chiral

Warfarin is a widely used oral anticoagulant which is mostly administrated as a racemic mixture containing equal amount of R- and S-enantiomers. The two enantiomers are shown to exhibit significant differences in pharmacokinetics and pharmacodynamics. In this study, a new

The capillary electrochromatographic separations of three acidic enantiomers (carprofen, coumachlor and warfarin) were studied on a capillary column packed with 5 microm (3R,4S)-Whelk-O 1 chiral stationary phase. The influence of several experimental parameters (mobile phase pH, type of background electrolyte

Racemic mixtures of five acidic drugs have been successfully separated by supercritical fluid chromatography (SFC) using macrocyclic antibiotic chiral stationary phases (CSPs). A ristocetin A CSP has been prepared 'in-house' and effectively applied in packed capillary SFC to separate the
