摘　　要：以超微粒分子筛对毛细管内壁进行改性，成功地制备了不同极性的ＳＣＯＴ柱。实验结果表明，以超微粒分子筛改性的毛细管色谱柱具有预想的特性，并可得到准确的定量结果，因此成为应深入探讨的新柱型。In this paper, a new type of SCOT column was successfully prepared with ultrafine zeolite. Several liquid phases with different polarity, such as, squalane,DC-550, DEGS were coated on the inner surface. The ultrafine zeolite has characteristics of fine and uniform particle, large specific surface area,regular crystal structure and similar chemical constitution to glass. This new type of SCOT column showed satisfactory features in separation property,quantitative accuracy,inertness and heat stability etc.
