Abstract:

A novel reversed/hydrophilic chromatographic stationary phase based on dialdehyde microcrystalline cellulose (DMCC)-functionalized C18 was prepared by covalent bonding between the amino groups of octadecylamine with the aldehyde groups of DMCC, which was used in reversed-phase liquid chromatography (RPLC) and hydrophilic interaction liquid chromatography (HILIC) modes. The prepared DMCC-functionalized C18 modified silica (C18-DMCC/SiO2) stationary phase exhibited good hydrophobic selectivity and aromatic selectivity by separating alkylbenzenes and polycyclic aromatic hydrocarbons (PAHs) in the RPLC mode. Polar compounds, including anilines, phenols, and glycosides were chosen as analytes to evaluate the polar selectivity of this column in the RPLC mode, and the evaluation results were satisfactory compared with the commercial C18 column. Nucleobases were used for evaluating the hydrophilic interaction liquid chromatography performance of the C18-DMCC/SiO2 column. By investigating the impact of organic solvent content on the retention, it could be found that this new stationary phase had the typical characteristics of reversed-phase/hydrophilic chromatography.
