COSMOSIL PBB is a pentabromobenzyl group bonded silica based column useful for preparative-scale separation of fullerenes. It can be used with carbon disulfide or 1,2,4-trichlorobenzene, which has greater solubility for fullerenes than toluene. The loading capacity of COSMOSIL PBB for C60 and C70 can be three times greater than COSMOSIL Buckyprep.
