HPLC high performance liquid modification

They are then quantitated by High Performance Liquid Chromatography (HPLC) equipped with an amine column and UV detector. This procedure is a modification of the Ciba-Geigy AG-417A method. [Pg.1]

The EOF can also be controlled by chemical modification of the capillary surface. Various options initially developed for modification of silica in high performance liquid chromatography (HPLC) and for coating capillaries in gas chromatography (GC) are available for the chemical coating of capillaries. The surface silanols at the capillary wall can be reacted with silanes introducing anchor... [Pg.194]

The developments of the Lewis base-modified zirconia and mixed-oxide containing zirconia as stationary phases for high-performance liquid chromatography (HPLC) are reviewed. In this context, the preparation methods of porous spherical zirconia, and zirconia supports for HPLC based on modification with fluoride, phosphate, phos-phonate, carboxylic acid, phenols, and protein, as well as cyclodextrin derivative, are covered. The application of modified-zirconia in capillary electrochromatography (CEC) is also discussed. [Pg.914]

Sugars. The high performance liquid chromatography (HPLC) method described by Hunt et al. (8) was used to determine the sugars in the kiwifruit and nectars with some modifications (21). A Waters Association Chromatograph equipped with a Model 6000-A solvent delivery system, a Model R401 refractometer detector, a D6K universal injector column was a 30 cm x 4 mm i.d. stainless steel tube packed with u-bondapak-carbohydrate (Waters Associates). The precolumn was packed with CO-PELL PAC (Whatman). The eluent was acetonitril and distilled water (85/15, v/v). [Pg.308]
