Title:
SILICA SPHERICAL BODY AND AFFINITY CARRIER
Document Type and Number:
WIPO Patent Application WO/2013/062105
Kind Code:
A1
Abstract:
Provided is an affinity carrier having a low pressure loss and a high binding capacity, even when the linear flow rate of a solution passing through the carrier is fast. Also provided is a silica spherical body having (a) according to laser light scattering, an average particle diameter of 30 to 40 µm, (b)according to measurement by a Coulter counter, a ratio (D10/D90) of 1.50 or less, where D10 is 10% and D90 is 90% beginning from the smallest cumulative volume of the particle diameter distribution, and (c) according to mercury porosimetry, an average micropore diameter of between 85 to 115 nm and a micropore volume of 1.5 mL/g or greater as determined by mercury porosimetry.
