Title:
POROUS SILICA POWDER
Document Type and Number:
WIPO Patent Application WO/2014/034588
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a porous silica powder which is suitable for a carrier for gas chromatography, and the like. This porous silica powder is configured to have an average pore diameter of 0.5-10 μm as determined by a mercury intrusion method, a pore volume of the pores having pore diameters of 100 nm or less of 0.2 cm3/g or less as determined by a nitrogen gas adsorption method, a specific surface area of 0.5-100 m2/g as determined by a nitrogen gas adsorption method, and a particle size distribution of 10-1,000 μm.
