  • Publication number: 20240278212
    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 (ΒΌ? inner diameter), capillary micro-LC ( 1/16?), or nan-LC (( 1/32?).

  • Patent number: 12037318
    Abstract: The method of making a wall-coated open tubular capillary column with a poly benzyl stationary phase is a method of preparing a capillary column for gas chromatography. An inner wall of a fused silica capillary column is cleaned and then rinsed with a sodium hydroxide solution. The fused silica capillary column is flushed with isopropanol to form a pre-treated capillary column, and the pre-treated capillary column is loaded with a mixture of phenyl tri-methoxy silane and alcohol. The loaded pre-treated capillary column is heated to form a treated capillary column, which is then washed. A thin layer of a poly benzyl stationary phase is then coated on the inner wall through condensation polymerization of benzyl chloride monomers with a Lewis acid catalyst in a non-polar solvent.
