11/906859

Inventors:

Chen Wang - Midland MI, US
Carey L. Scortichini - Midland MI, US
Todd S. Bridson - Midland MI, US

Assignee:

Dow AgroSciences LLC - Indianapolis IN

International Classification:

C25B 3/00

US Classification:

205426, 205440

Abstract:

International Classification:

B01D 15/08

US Classification:

2101982, 2105021, 210635, 210656, 502404

Abstract:

The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
