“…When employing a dual selector system, with a mix of charged and uncharged CDs, good resolution and high numbers of theoretical plates were obtained (Table 1, Fig. 4), which is in accordance with earlier findings [20,26]. On the coated capillary, the elution order of the enantiomers was reversed using the same conditions except for polarity and applied voltage (Fig.…”

“…Negatively charged CDs have been found to be effective as chiral selectors for the enantiomeric separation of propranolol [10,14,20,[26][27][28][29]. At pH 6.5, the interaction between the negatively charged CD and the cationic propranolol (pK a = 9.5) is believed to arise through a combination of ion-pairing complexation and hydrophobic inclusion in the cavity of the CD [27,30].…”

“…There are some important factors, which improve the robustness and reproducibility of the migration times, (i) replenishment of the BGE and chiral selector after few runs, e.g., two runs [88], (ii) control of the capillary temperature and if possible temperature of the vial carrousels, and (iii) modification of capillary wall [277] and pretreatment of the capillary prior each run.…”

“…The Official method [2] for the determination of ABH is non-aqueous titration technique detecting the end point potentiometrically in aqueous medium using 0.1M NaOH titrant. Several methods are reported in the literature for the determination of the beta-blockers including spectrophotometry [3][4][5][6][7], NMR [8,9], high performance liquid chromatography [10][11][12][13], thin layer chromatography [14], liquid chromatography [15,16], capillary electrophoresis [17][18][19][20][21], pharmacokinetics [22,23], and fluorescence [24]. The reported spectrophotometric methods [4][5][6] do not discuss the stability of the methods and at the same time have low sensitivity [3][4][5][6].…”
