The large surface area and the high hole ratio silica shell filler, and of producing that the method of possessing narrow grain size and hole diameter distribution

摘要

Topic The large surface area which possesses the narrow particle and hole diameter distribution, offer the formation method and the compound of the meso porous silica beads LC shell filler of high hole ratio. SolutionsThis invention is something regarding the LC packing material in the whole, especially is something regarding the HPLC packing material of the silica bases. In addition, formation method and usage of the packing material are disclosed. The HPLC packing material by this invention, the large surface area, has featured high hole ratio and satisfactory mechanical strength. As for this, in part, it is due to the part content of the surface active agent in adjusting the LC packing material. Character of these desires, part originates in the range where the hole diameter which is formed at the time of adjusting the packing material is narrow.
