The automatic procedures for optimizing the composition of a binary mobile phase in reversed phase liquid chromatography have been intensively studied for the past ten years. The performance of these procedures, based on either the black box approach or on other methods such as the experimental desi
## Abstract The influence of the mobile phase on retention is studied in this paper for a group of over 70 compounds with a broad range of multiple functional groups. We varied the pH of the mobile phase (pH 3, 7, and 10) and the organic modifier (methanol, acetonitrile (ACN), and tetrahydrofuran (
## Abstract A novel straightforward approach to selective separation for flavonoid compounds was reported. The solid phase material was prepared by copolymerization using allylβbromideβmodified chitosan as macromonomer, and ethylene glycol dimethacrylate as crossβlinker. The material was evaluated
## Analysis of selected ionic liquid cations by ion exchange chromatography and reversed-phase high performance liquid chromatography The chromatographic behavior of 8 ionic liquids -7 homologues of 1-alkyl-3-methylimidazolium and 4-methyl-N-butylpyridinium -has been investigated with a strong cati
