| 英文摘要 | a facile method to prepare a polar stationary phase for hydrophilic interaction chromatography (hilic) was proposed by coating polyvinyl alcohol onto silica particles (pva-sil). a water or organic solvent-insoluble permanent pva coating on the silica particle surface can be formed simply by dipping silica particles into a hot pva solution and then settled from this solution, leaving a thin layer of pva coating and frozen in a freezer. the pva-sil shields the silica core from solution erosion to some degree and the ph tolerance range was extended to 9.5 from 8.0 for bare silica. pva-sil demonstrated a good hydrophilic property for several kinds of polar compounds and similar to 57000 m(-1) of plate count was achieved. this method can also be extended as a universal method to prepare various stationary phases with exchangeable functionalities by doping the desired ingredient in a pva solution. |
