Native RPLC For ADCs: How Column Hydrophobicity Shapes DAR Separation

ADC characterization can quickly become a bottleneck when intact mass analysis has to account for multiple drug-to-antibody ratio species, positional isomers, and residual formulation components. A more targeted chromatographic approach can help separate that complexity before it reaches the mass spectrometer, making it easier to interpret results with confidence. By using a column designed specifically for ADC analysis, teams can improve resolution, reduce sample-related ambiguity, and gain a clearer view of critical quality attributes that matter for development and manufacturing decisions. For scientists working to streamline ADC workflows, the right column chemistry can turn a crowded, difficult-to-read profile into more usable analytical insight.
