Macherey-Nagel GmbH
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.
-
For higher demands on the performance of column packings we recommend the high-purity irregular POLYGOPREP silicas.
-
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 1319-58T.
-
The 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.
