Agilent 300 SCX Analytical HPLC Column 4.6 x 250 880952-704

The Agilent ZORBAX 300 SCX (part number 880952-704) is a strong cation-exchange (SCX) analytical HPLC column (4.6 × 250 mm) packed with 5 µm, fully porous ZORBAX silica having 300 Å pores. It is intended for high‑efficiency ion‑exchange separations and purification of basic, water‑soluble compounds and biomolecules such as peptides and proteins, and is designed for rapid gradients and fast re‑equilibration in LC workflows.

Key Features:

• Phase: Strong cation exchange (300 SCX).
• Dimensions: 4.6 mm inner diameter × 250 mm length.
• Particle size: 5 µm, fully porous spherical silica.
• Pore size: 300 Å.
• pH range: 2–7.
• Maximum temperature: 80 °C; Maximum pressure: 350 bar.

Advantages:

• High mechanical stability supports use at elevated flow rates and pressures for faster analyses.
• Stable operation across pH 2–7 and compatibility with organic mobile‑phase modifiers enable flexible method development.
• Large 300 Å pore size combined with 5 µm particles gives efficient, biomolecule‑friendly separations suited to peptides and proteins.
