Gas phase silylation, a rapid method for preparation of high-performance liquid chromatography supports

Wikström, Per ; Mandenius, Carl Fredrik and Larsson, Per-Olof LU (1988) In Journal of chromatography. A 455. p.105-117
Abstract
A new method for preparing chromatographic supports is described. Porous silica was treated with gaseous silanes and gaseous triethylamine at high temperature and reduced pressure. The silylation procedure was rapid and gave supports with a covalently bound monolayer of aminopropyl-or epoxysilane. Diol silica prepared by gas phase silylation was compared with diol silica prepared in the aqueous or organic phase (toluene). Seven proteins were chromatographed and the protein recovery, plate number and peak asymmetry were calculated. Silica prepared by the gas phase silylation method showed improved performance. The separation of carbonhydrates on aminopropylsilica and the isolation of lactate dehydrogenase with nicotinamide-adenine... (More)

The separation of carbonhydrates on aminopropylsilica and the isolation of lactate dehydrogenase with nicotinamide-adenine dinucleotide-silica, prepared from gas phase silylated diol silica, are described.
