TSKgel Octyl-80Ts has a lower carbon load and hydrophobicity than the corresponding ODS products. The C8 alkyl ligand provides a unique selectivity for the analysis of low MW pharmaceuticals, bases, nucleosides and nucleotides. Featuring high purity, metal free silica and a proprietary technique for complete endcapping of residual silanol groups, TSKgel Octyl-80Ts columns reduce tailing when analyzing basic compounds. Common applications include purity checks and peptide mapping.

Bonded phase pore size is indicated by the number in the product description, in this case TSKgel Octyl-80Ts has 8nm nominal pore size.  The pore size of the base silica is 10nm.
