3 These interactions will result in changing elution patterns and may cause the invalid molecular weight calculations. It is important to reduce them in order to obtain the accurate molecular weight distribution. Hydrophobic interactionThe analyte is adsorbed into the packing material. This delays the analyte elution, and thus results in underestimation of its molecular weight (Figure B, D).Ionic interaction(1) Ion ExclusionThe analyte is repelled from the packing material. This accelerates the analyte elution, and thus results in overestimation of its molecular weight (Figure A, C)(2) Ion ExchangeThe analyte is adsorbed onto the packing material. This delays the analyte elution, and thus results in underestimation of its molecular weight (Figure B, D).Precautions for polar polymer analysisInteraction within and between the analyteIonic repulsion effects observed within the multivalent macromolecules causes structure expansionThis accelerates the analyte elution, and thus results in overestimation of its molecular weight (Figure A).
