Analyzing complex peptide mixtures, especially those rich in polar sequences, demands column chemistries that balance selectivity with broad retention.
Biozen Peptide Polar-C18 is a reversed-phase column engineered to enhance retention of polar peptides while preserving critical non-polar interactions for comprehensive peptide mapping and quantitation.
Built on Phenomenex’s thermally modified particle technology, it offers greater peak capacity, sharper peak shapes, and reliable reproducibility—ideal for challenging digests like mAbs, ADCs, and other biologics.
