Brownlee Aquapore C8 columns are based on wide pore 300Å 7µm silica, for the analysis of large bio-molecules. Requires holder P/N 07150013 without guard column. If a guard column is being used P/N 07150018 and P/N 07150002 will also be required.
Brownlee Aquapore columns are built on large pore (300 Å) silica for the analysis of large biomolecules such as peptides and proteins. Large pore stationary phases are required for the analysis of large molecules because the analytes need to penetrate the pores to improve retention and resolution. The RP-300 is a reverse-phase C8; AX-300 is a weak anion exchanger that is composed of a crosslinked polyethyleneimine phase bonded on the silica surface. The reverse-phase columns are also available in microbore (1.0 mm ID) for increased sensitivity and better compatibility with LC/MS interfaces.
