The Agilent ZORBAX 300 Extend-C18 part number 763973-902 is a 4.6 x 150 mm, 3.5 µm reversed-phase HPLC column with a 300 Å, C18 bonded phase. It is designed for high-efficiency separations of peptides, polypeptides and small proteins and is supported for use in LC and LC–MS workflows. Manufacturer specifications emphasize wide-pore construction and extended pH stability (pH 2–11.5), enabling reliable separations at both low and high pH and improved LC–MS sensitivity with ammonium-hydroxide mobile phases.

Key Features:

  • Separation Mode: Reversed Phase (RP).
  • Chemistry/Phase: ZORBAX 300 Extend-C18 (C18 bonded phase).
  • Particle Size: 3.5 µm.
  • Pore Size: 300 Å (wide-pore).
  • Length: 150 mm.
  • Inner Diameter: 4.6 mm.
  • pH Range: 2–11.5 (manufacturer specified).

Advantages:

  • Extended pH stability allows peptide and small-protein separations at high and low pH for alternative selectivity and improved recovery.
  • Wide 300 Å pores and 3.5 µm particles provide high efficiency and good recovery of hydrophobic peptides and polypeptides.
  • Recommended compatibility with LC–MS using ammonium-hydroxide mobile phases can improve peptide ionization and sensitivity in MS workflows.
