Preparation of Glass Capillary Column Modified by Ultrafine Zeolite and Its Properties
超微粒分子筛改性的玻璃毛细管柱的研制

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.
