摘要：

The retention mechanism in hydrophilic interaction chromatography is supposed to involve partitioning of analytes between a mostly organic mobile phase and a water layer at the surface of the stationary phase. By molecular dynamics simulations, in which a 9 nm diameter bare silica pore is fed with H 2O/CH 3CN mixtures (see picture: 10:90 (v/v)), the water layer is elucidated and interpreted regarding the retention of hydrophilic analytes.
