Cosmosil PBB packed Columns

Click for Application Data

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.
