摘要
The preparation of the zeolite membrane PLOT capillary 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 PLOT columncompared with those on the coated zeolite PLOT column were reported. The reproducibility ofthe zeolite membrane PLOT column were evaluated. It has been found that the zeolitemembrane obtained is more homogeneous and thinner than coated zeolite. The zeolite membranePLOT column can shorten the analysis time, make the peak more symmetric, allowseparation at lower temperature and broaden the range of utilization of zeolites in GC.
