A silica-based stationary phase for chromatography columns and the methods of preparing such. More particularly, but not by way of limitation, a silica-based stationary phase that is substantially free of polyethers (e.g., polymer glycols). Also, a chromatography column comprising a silica-based stationary phase substantially free of polyethers (e.g., polymer glycols) within its channels as either a thin-film coating and/or a monolith and/or a monolithic coating. More particularly, a micro-electro-mechanical system (MEMS) chromatograph comprising a silica-based monolith substantially free of polyethers (e.g., polymer glycols) as the stationary phase within the micro-channels of the column.
A method for the formation of a silica-based stationary phase for a chromatography column having an internal surface and a volume, wherein the silica-based stationary phase substantially fills the chromatography column forming a monolithic stationary phase within the chromatography column comprising a monolith encompassing between 50 to 100% of the volume of the chromatography column and at least a portion of the internal surface is in contact with a polymerized sol-gel comprising reaction products of a silica precursor, a polyether, and a solvent, the method comprising:
