An inorganic-organic hybrid affinity monolithic column was synthesized by a novel "one-pot" approach. The resulting hybrid affinity monoliths have potential applications in specific recognition and enrichment of glycoproteins.
Stephan Altmaier et al.
Journal of separation science, 31(14), 2551-2559 (2008-07-12)
Silica-based monolithic columns were prepared for HPLC with systematic variations of the tetramethoxysilane (TMOS) and polyethylene oxide (PEO) content as reactants in a sol-gel process accompanied by phase separation. The resulting monoliths showed differences in the macropore and silica skeleton
Shota Miyazaki et al.
Journal of chromatography. A, 1218(15), 1988-1994 (2010-12-24)
Chromatographic properties of a new type of monolithic silica rod columns were examined. Silica rod columns employed for the study were prepared from tetramethoxysilane, modified with octadecylsilyl moieties, and encased in a stainless-steel protective column with two polymer layers between

A simple capillary flow porometer (CFP) was assembled for through-pore structure characterization of monolithic capillary liquid chromatography columns in their original chromatographic forms. Determination of differential pressures and flow rates through dry and wet short capillary segments provided necessary information
Josef Planeta et al.
Journal of chromatography. A, 1217(36), 5737-5740 (2010-08-03)
The temperature effects during the sol-gel process and ageing of the silica-based monolith on the structure and separation efficiency of the capillary columns (100microm i.d., 150mm) for HPLC separations were studied. The tested columns were synthesized from a mixture of
