The Agilent ZORBAX Eclipse Plus C18 (part number 959961-902) is a reversed‑phase HPLC analytical column (4.6 x 100 mm, 3.5 µm) designed for routine and method‑development separations of acids, bases and neutral compounds. It uses Eclipse Plus C18 chemistry with optimized endcapping to provide high resolution, reproducible peak shape and is commonly used in pharmaceutical, food and environmental analyses.

Key Features:

  • Dimensions: 4.6 mm ID × 100 mm length (analytical format).
  • Particle size: 3.5 µm, fully porous silica particles.
  • Pore size: 95 Å.
  • pH operating range: 2–9 (recommended limits; reduced lifetime above pH>7/high temp).
  • USP classification: L1 (C18, octadecyl).
  • Carbon load: ~9%; Endcapped: double; Pressure rating: ~400 bar.

Advantages:

  • Consistent, excellent peak shape for acids, bases and neutrals due to optimized bonding and endcapping, aiding method development and transfer.
  • Broad pH range (2–9) and temperature guidelines permit versatility across pharmaceutical, food and environmental assays.
  • USP L1 designation facilitates method compliance and transfer between labs.
  • Robust fully porous 3.5 µm particles deliver high resolution while remaining compatible with standard HPLC pressures (~400 bar).
