Effect of silica gel modification with cyclofructans on properties of hydrophilic interaction liquid chromatography stationary phases

Popis výsledku v původním jazyce

Hydrophilic interaction liquid chromatography (HILIC) offers very good possibilities for separation of polar compounds as an alternative to reversed phase HPLC where polar compounds are not sufficiently retained. HILIC is becoming more popular for the analysis of biologically interesting (active) analytes. Various stationary phases are commercially available however, development of new materials (sorbents) suitable for HILIC systems still continues. Silica gel columns can be used directly but their modification can improve separation ability of the stationary phases. Cyclofructan-based stationary phases are demonstrated as possible HILIC columns in this work. The effect of silica gel modification by cyclofructan and a derivatized cyclofructan was studied in detail. HILIC separation systems with silica gel, cyclofructan and isopropyl cyclofructan modified silica stationary phases were compared. The detailed study of chromatographic behavior of peptides revealed that multimodal retention
