摘要：

The influence of column temperature and pressure on the planarity selectivity of encapsulated and polymeric octadecylsilane-modified silicas was examined using carbon dioxide mobile phase in supercritical fluid and liquid chromatography. The use of liquid carbon dioxide was found to enhance remarkably the molecular planarity recognition capability of the polymeric stationary phase compared with supercritical conditions. The influence of pressure and temperature on selectivity was seen to be significant with the polymeric phase but less with the encapsulated. It seems that pressure and temperature change the morphology of the polymeric phase to a greater extent than the encapsulated one.
