Abstract:
A broad appraisal of the kinetic performance of organic polymeric monolithic columns is reported using commercially available poly(styrene-co-divinylbenzene) monolithic columns (Dionex ProSwift RP-1S). Analysis of a protein digest sample at elevated temperatures (> or =80 degrees C) indicated no apparent analyte degradation using an inert polymeric stationary phase. Comparison between low molecular weight solute and peptide separations highlighted the markedly different mass transport processes observed on macroporous monolithic beds and an improved C term at elevated temperature in both instances. The current usefulness of this column format for biomolecule analysis was further studied via employment of a kinetic performance characterisation for the first time to provide direction for column development servicing this application.
