Siloxane-immobilized particulate stationary phases for chromatographic separations and extractions

摘要

Chromatography and solid phase extraction devices having immobilized stationary phases are disclosed. An exemplary device of the Invention includes a column or cartridge packed with a mixture of a particulate stationary phase material and a polymeric network of Cross-linked poly(diorganosiloxane), e.g., poly(dimethylsiloxane). The Invention also provides methods of making and using such devices.
