| Abstract: | 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. |
