Abstract
In this work, a novel sulfated-β-cyclodextrin (S-β-CD) coated stationary phase was prepared for open-tubular capillary electrochromatography (OT-CEC). The capillary was developed by attaching polydopamine/sulfated-β-cyclodextrin (PDA/S-β-CD) onto the gold nanoparticles (AuNPs) coated capillary which was pretreated with polydopamine. The results of scanning electron microscopy (SEM) and energy dispersive X-ray analysis spectroscopy (EDS) indicated that polydopamine/sulfated-β-cyclodextrin was successfully fixed on the gold nanoparticles coated capillary. To evaluate the performance of the prepared open tubular (OT) column, the enantioseparation was carried out by using ten chiral drugs as model analytes. Under the optimal conditions, salbutamol, terbutaline, trantinterol, tulobuterol, clorprenaline, pheniramine, chlorpheniramine, brompheniramine, isoprenaline and tolterodine were baseline separated with the resolution (Rs) values of 3.25, 1.76, 2.51, 1.89, 3.17, 2.17, 1.99, 1.72, 2.01 and 3.20, respectively. Repeatability of the column was studied, with the relative standard deviations for run-to-run, day-to-day and column-to-column lower than 5.7%.
