TSKgel BioAssist Phenyl is the PEEK format of the TSKgel Phenyl-5PW column for samples that may adsorb to stainless steel. This column is based on a 100 nm pore size polymethacrylate base material bonded with phenyl groups. The TSKgel BioAssist Phenyl column is stable in either acid or caustic cleaning regimens and provides excellent access to larger molecules with low diffusion coefficients.
Being the most hydrophobic among the three TSKgel HIC columns, TSKgel BioAssist Phenyl is an excellent choice to screen for the selectivity, retention and recovery of most biomolecules.
