Abstract: The preparation of the zeolite membrane PLOTcapillary column by in situsynthesis was described. The advantages of this new kind of column were discussed. Someanalytical application to the separation of various mixtures on zeolite membrane PLOTcolumncompared with those on the coated zeolite PLOTcolumn were reported. The reproducibility ofthe zeolite membrane PLOTcolumn were evaluated. It has been found that the zeolitemembrane obtained is more homogeneous and thinner than coated zeolite. The zeolite membranePLOTcolumn can shorten the analysis time, make the peak more symmetric, allowseparation at lower temperature and broaden the range of utilization of zeolites in GC.

Key words: Gas chromatography, Zeolite membrane PLOT column, In situ synthesis
