Progress in Certified Reference Materials for Specific Surface Area ,Pore Structures of Porous and Highly Dispersed Materials

The certified reference materials for specific surface area, pore structures of porous and highly dispersed materials play an important role in instrument calibration, method validation and product quality control, etc. The principles of determining specific surface area, pore structures of porous and highly dispersed materials by using physisorption and mercury intrusion methods were briefly introduced, including the present situation of some corresponding analytical standards. The overseas present status of certified reference materials for specific surface area, pore structures of porous and highly dispersed materials by using physisorption and mercury intrusion methods were also discussed, and the shortcomings and some suggestions on developing our these certified reference materials were indicated.
