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.
