Abstract
The chromatographic column is a stainless steel column having a stationary phase of porous monolithic polymer chemically bonded to the interior wall of the stainless steel column so that the stationary phase is fixed and immobile and does not require frits or other seals to retain particulate matter or a slurry in the column. The inner wall of the column is oxidized and then vinylized with a difunctional linker to chemically bond the polymer to the column. The difunctional linker may be 3-(trimethoxysilyl) propyl methacrylate, vinyl trimethoxysilane, 3-mercaptopropyl trimethoxysilane, or glycidoxypropyltrimethoxysilane. The monolithic polymer is prepared in situ in the column by radical polymerization of a monovinyl monomer with a crosslinking divinyl monomer. The column may be a conventional stainless steel column (¼″ inner diameter), capillary micro-LC ( 1/16″), or nan-LC (( 1/32″).
