Silica Adsorbents For Column Chromatography

FEATURES :

• Standard silica 60, pore size ~ 60 Å, pore volume ~ 0.75 mL/g, spec. surface BET ~ 500 m2/g; highly porous, amorphous silicic acid in the form of hard, opalescent particles, prepared by precipitation of water glass with sulfuric acid

• Silica FIA for the fluorescence indicator adsorption procedure for the determination of hydrocarbon groups in the testing of liquid fuels in accordance with DIN 51791 and ASTM D 1319-58TThe FIA method determines saturated hydrocarbons, olefins and aromatic hydrocarbons of a sample chromatographically by adsorption and desorption in a column filled with FIA silica, in the presence of a fluorescent dye mixture
