BioZen Peptide-XB-C18

BioZen Peptide-XB-C18

Digested mAbs or ADCs typically include a large body of compounds which are crucial to understanding post translation modifications. So we designed our Biozen™ Peptide columns to offer highly useful and unique retention profiles. Biozen Peptide XB-C18 allows for fast and effective elution windows by utilizing core-shell particles to gain sharper peaks, better peak capacities, and overall higher sensitivity.

Biozen Peptide columns provide:

  • Unique retention profiles
  • Greater peak coverage
  • High efficiency on both HPLC and UHPLC

Separation Mode
