Retention Mechanisms of Basic Compounds in Liquid Chromatography with Sodium Dodecyl Sulfate and 1-Hexyl-3-Methylimidazolium Chloride as Mobile Phase Reagents in Two C18 Columns

open access: yesSeparations
Reversed-phase liquid chromatography (RPLC) relies on a non-polar stationary phase and a more polar hydro-organic mobile phase, where compound retention is primarily governed by hydrophobicity, with more hydrophobic compounds being retained longer.

Estimation of Solute-Stationary Phase and Solute-Mobile Phase Interactions in the Presence of Ionic Liquids

open access: yesSeparations, 2019
The presence of free silanols on alkyl-bonded reversed-phase stationary phases is responsible for broad and asymmetrical peaks when basic drugs are chromatographed with conventional octadecylsilane (C18) columns due to ionic interactions. In the last few

Separation of Underivatized Amino Acids and Dipeptides Using 1- Butylimidazolium Based Stationary Phase and UV Detection [PDF]

open access: yes, 2004
Isocratic elution of aromatic amino acids was achieved using a butyl-imidazolium based stationary phase and UV detection. For this study butyl-imidazolium bromide was bonded to a silica substrate and packed into an HPLC column.

4-Vinylpyridine–Trimethylolpropane Trimethacrylate Composite Polymer Particles and Their Application as Adsorbents

open access: yesAdsorption Science & Technology, 2015
The study describes the synthesis of microspheres of 4-vinylpyridine (4VP) and trimethylolpropane trimethacrylate (TRIM) with uniform diameters. Polymeric 4VP–TRIM microspheres were prepared by seed polymerization, using polystyrene beads as a shape ...
