Zt. Jiang et Ym. Zuo, Synthesis of porous titania microspheres for HPLC packings by polymerization-induced colloid aggregation (PICA), ANALYT CHEM, 73(3), 2001, pp. 686-688
Porous titania microspheres with a very narrow particle size distribution (
PSD) were synthesized by polymerization-induced colloid aggregation (PICA).
After being sintered, the titania microspheres that are obtained have an a
verage diameter of 3.5 mum, a surface area of 36.7 m(2)/g, an average pore
volume of 0.30 mL/g, and an average pore diameter of 32.2 nm. The microsphe
res possess enough rigidity to withstand high packing pressure and are very
useful as a new kind of chromatographic packing material for high performa
nce liquid chromatography (HPLC).
