COSMOSIL Buckyprep is a pyrenylpropyl group bonded silica based column specifically designed for fullerene separation. The unparalleled separation capabilities have enabled COSMOSIL Buckyprep to become the world benchmark of HPLC column for fullerene separation. COSMOSIL Buckyprep retains fullerenes very strongly with a mobile phase of 100% toluene and exceeds the injection volume of a standard C18 column by a factor of 35. Therefore, preparative-scale separation can be obtained with a 250 mm x 4.6 mm I.D. analytical column.
