Agilent Eclipse XDB-Phenyl 5u, 4.6 x 150mm 993967-912

The Agilent ZORBAX Eclipse XDB-Phenyl (part number 993967-912) is a reversed‑phase HPLC analytical column with a phenyl bonded phase designed for method development and routine separations. The column is 4.6 x 150 mm with 5 µm fully porous particles and provides the phenyl selectivity of the Eclipse XDB family while delivering improved peak shape for basic, acidic and neutral compounds. It is intended for general HPLC applications where phenyl selectivity and robust, reproducible performance across a wide pH range are required.

Key Features:

• Phase: Eclipse XDB-Phenyl
• Dimensions: 4.6 mm ID x 150 mm length
• Particle size: 5 µm (fully porous)
• Pore size: 80 Å
• pH range: 2–9
• Pressure rating: 400 bar
• USP designation: L11

Advantages:

• Extra‑densely bonded, double end‑capped chemistry reduces silanol interactions and improves peak shape for a wide range of analytes.
• Wide pH tolerance (2–9) enables method development across low and mid pH conditions without changing column family.
• 400 bar pressure rating and conventional HPLC hardware compatibility allow use on standard analytical systems.
• Phenyl selectivity (Eclipse XDB-Phenyl) provides complementary retention/selectivity for aromatic and π‑interacting compounds during method development.
