Title: Ralf J Oerschkes: Innovator in Gel-Permation Chromatography
Introduction
Ralf J Oerschkes is a notable inventor based in Willich, Germany. He has made significant contributions to the field of gel-permation chromatography, holding a total of 3 patents. His work focuses on developing advanced column-packing materials that enhance the efficiency and effectiveness of chromatography processes.
Latest Patents
Oerschkes' latest patents include innovative methods for creating column-packing materials specifically designed for gel permeation chromatography (GPC). These materials consist of support particles with a mean particle diameter ranging from 1 to 50 micrometers. The matrix is formed from either inorganic or organic, polymeric, and porous hard materials, featuring a mean pore diameter of 6 to 50 nanometers and a pore volume of 0.1 to 3 ml/g. The unique aspect of his invention is that the polymer chains within the matrix are linear, permeable, and not crosslinked, with an upper exclusion limit between 200 and 200,000. This design allows the pores of the matrix to be entirely filled by the polymer chains, which are chemically bound to the pore surfaces and permeable to solvents and partially to dissolved substances.
