Enantioseparation in high performance liquid chromatography: preparation and evaluation of a vancomycin-based chiral stationary phase via surface-initiated atom transfer radical polymerization

Abstract

The chromatographic technique based on chiral stationary phase (CSP) has been explored for enantioseparation. Herein, poly(glycidyl methacrylate) (poly(GMA)) brushes were grafted on the surface of silica gel via surface-initiated atom...

Preparation and chromatographic evaluation of a mixed polymer brush–silica stationary phase with temperature-sensitive property

“…Characterization of the silica@poly(Qun-co-VCl) stationary phases SI-ATRP is a controlled living radical polymerization technique which allows for precise controlled polymerization with low polydispersity and controlled chain length. 34 Hence, for the preparation of a stationary phase by SI-ATRP, it can efficiently control the graing amounts of functional monomers to induce the appropriate interaction force with the analytes, creating superior separation. 35 The preparation procedure for the stationary phase is shown in Fig.…”

Carbon dot-functionalized macroporous adsorption resin for bifunctional ultra-sensitive detection and fast removal of iron(iii) ions

“…After the catalyst of CuBr (12 mg) was added, the freezing, evacuating and thawing operations were further performed 3 times. 32 Then, the reaction was performed at 60 °C for 6 h. Finally, the resulting material, assigned as MAR@poly(PA), was washed with ethanol, EDTA–2Na solution (0.1 mol L −1 ) and deionized water, respectively, and dried in a vacuum.…”
