These columns have been designed following the high demand for suitable analytical methods for process monitoring and quality control of wide pore biomolecules. Accurate analysis of proteins, antibodies and large peptides requires columns with good permeability, along with better mass transfer and selectivity. In order for size exclusion not to influence the separation, the pore size should be approximately ten times larger than the molecule being analysed.
