Monolithic-shaped bodies for purifying and separating biopolymers

摘要

The present invention concerns new monolithic shaped bodies, a method for their preparation as well as their use especially for the selective purification and separation of biopolymers. A chromatographic separation material is provided with the new monolithic shaped bodies that allows a selective, efficient and reproducible purification and separation of biopolymers.

主权项

1. A filter and separation monolithic shaped body comprising silicon dioxide, macropores and borate having a weight fraction of 0.1 to 0.3% boron obtained by a method comprising the following process steps:
a) placing silicon dioxide into a reaction vessel; b) adding solution A comprising at least one or more alkali silicate(s) and potassium borate, c) adding solution B comprising at least one or more porogen(s) and water, d) adding at least one organic amide to create a reaction mixture, and e) drying the reaction mixture, thereby forming said macropores.
