The adsorption effect of capillary wall, which was usually considered as a troublesome factor, has been used as driving force for preparing stationary phase for open tubular capillary electrochromatography (OTCEC).

• 首次将管壁吸附作用作为开管毛细管电色谱固定相制备的推动力，成功地建立了称为“吸附固定相开管毛细管电色谱”的一种新方法。 原理是：选择合适的条件，让荷正电的化合物在毛细管管壁上充分吸附，直接用吸附层作为固定相。
