Various polar stationary phases are available for hydrophilic interaction chromatography
(HILIC) and help drive continuous applications in biomedical, environmental, and …

The composites of covalent organic frameworks (COFs) and silica gel have been considered
to be promising chromatographic separation materials due to the distinct advantages such …

Hydrophilic interaction liquid chromatography (HILIC) today is a well-known and largely
applied technique to analyse polar compounds such as pharmaceuticals, metabolites …

Abstract Chitosan and poly (1-vinylimidazole) are both potential adsorbents to remove Cr
(VI). Here, we designed the preparation of new adsorbents by combining chitosan and poly …

Covalent organic frameworks (COFs) have showed expected potential in chromatographic
separation due to unique structure and excellent performance. Nowadays, COF materials …

Stationary phases with mixed-mode mechanisms have emerged as a hot research topic. In
the present research, monodisperse core–shell UiO-67@ SiO2 materials were prepared and …

A zwitterionic stationary phase comprising pyridinium cations and sulfonate anions was
successfully developed through thiol-ene click chemistry. Using seven polar small …

In this study, a novel piperidinium-sulfonate based zwitterionic hydrophilic monolith was
prepared through thermally initiated co-polymerization of a piperidinium-sulfonate monomer …

A polymeric reversed-phase/weak anion exchange (Poly-RP/WAX) mixed-mode stationary
phase has been prepared by coating of a poly (3-mercaptopropyl) methylsiloxane film on …

We described two novel zwitterionic polymer-terminated porous silica stationary phases
containing the same pyridinium cation and anions of different side chains (carboxylate and …
