Different approaches for the separation of a set of nucleosides and nucleobases using capillary zone electrophoresis (CZE) and micellar electrokinetic chromatography (MEKC) are described. Several electrolyte compositions have been tested for this purpose. The addition of appropriate amounts of borate to the carrier electrolyte allowed manipulating migration orders in CZE and MEKC by selective complexation...
The performance of dopant-assisted atmospheric pressure photoionization (DA-APPI) and electrospray ionization (ESI) for the coupling of micellar electrokinetic chromatography (MEKC) with ion trap mass spectrometry (ITMS) was compared using a set of test drugs comprising basic amines, steroids, esters, phenones and a quaternary ammonium compound. The influence of the surfactant sodium dodecyl sulfate...
