PREPARATION AND CHARACTERIZATION OF ZEOLITE MEMBRANE GAS-LIQUID CAPILLARY COLUMN

Various stationary phases with different polarity have been coated eve nly on the surface of in situ synthesized zeolite membrane, The zeolit e membrane modified gas column has been prepared, Some characteristics of this new kind of column such as column efficiency, separating powe r, quantitative accuracy and thermostability of stationary phase have been evaluated, Large-bore zeolite membrane SCOT column has also been parpared in order to replace the packed column in regular analysis, It s column capacity and separation power under the condition of split st ream and no supplemental gas have been studied.
