摘要
以原位合成法制备的分子筛膜对玻璃毛细管内壁进行改性后，成功地制备了常现口径及大口径分配型SCOT柱，并对毛细管柱的性能进行了评价．
Various stationary phases with different polarity have been coated evenly on thesurface of in Situ synthesized zeolite membrane. The zeolite membrane modified gas columnhas been prepared. Some characteristics of this new kind of column such as columnefficiency, separating power, quantitative accuracy and thermostability of stationary phasehave been evaluated. Large-bore zeolite membrane SCOT column has also been parpared inorder to replace the packed column in regular analysis. its column capacity and separationpower under the condition of split stream and no supplemental gas have been studied.
