涂渍极性及强极性固定相硅膜改性弹性玻璃毛细管柱的研制

Flexible Glass Capillary Column Modified by Silicon Film With Polar and Strong-polar Stationary Phase of Chromatography

本工作研究了极性、强极性固定液直接涂渍在硅膜改性弹性玻璃毛细管内壁上,经优化温度老化色谱柱,成功地研制出OV-225、DEGS、Silar5、Silar9、Silar10等硅膜改性弹性玻璃毛细管柱。各种柱子均具有柱效高、惰性好、热稳定性好的色谱性能。

Polar and strong-polar stationary phases, OV-225, DECS, Silar 5,Silar 9, Silar 10, were directly coated on flexible glass capillary column modified by silicon film through electing suitable ageing temperature of column. The type of polar and strong-polar columns prepared posseses good chromatographic performance. Column efficiency, inertness and thermal stability of the columns were all nice.
