摘要:
With the introduction of new capillary column coating technique.It has been realized to prepare gas chromatograph of very high resolution. There has been continued interest in extending the use of GSC adsorbent to capillary chromatography. Currently the film built up on the inner surface of the capillary column can be quite homogeneous and the separation efficiency of the column is increased as well. There have been numerous papers that describe the preparation of PLOT columns in detail. However, Owing to the complexity of the preparation of porous layer for capillary GSC. It is still urgently need to extensively study the preparation process in order to get desired capillary columns of high quality and good reproducibility. This paper describe a new coating method of high performance PLOT columns with alumina by means of liquid phase deposition other than dynamic or static coating techniques. The selectivity, reproducibility and separation power of the column in analysis of light hydrocarbons were examined.
