The COSMOSIL® PBB packed column employs PentaBromoBenzyl as stationary phase. This phase offers different retention characteristics than COSMOSIL® C18, PYE or NPE. The COSMOSIL® PBB is especially useful for the preparative separation of fullerenes. It allows the use of carbon disulfide and/or 1,2,4-trichlorobenzene as eluent. This is advantageous to the separation because these solvents exceed toluene in the solubility of fullerenes. The COSMOSIL® PBB improves efficiency of the preparative separation of fullerenes including higher fullerenes, metallofullerenes and their derivatives.
