The Agilent ZORBAX Extend‑C18 column (part number 727700‑902) is a reversed‑phase UHPLC analytical column designed for high‑pH separations of basic small molecules and peptides; it uses a bidentate C18 bonding and double endcapping to protect silica at elevated pH. The column is supplied as 2.1 x 50 mm with 1.8 µm fully porous particles and is intended to improve peak shape, resolution and sensitivity in LC/MS methods when using high‑pH mobile phases (for example ammonium hydroxide).
Key Features:
- Phase: ZORBAX Extend‑C18 (bidentate C18, double endcapped).
- Dimensions: 2.1 mm ID × 50 mm length.
- Particle size: 1.8 µm (fully porous).
- Pressure rating: 600 bar (1.8 µm RRHT configuration).
- pH range: stable from pH 2 to pH 11.5.
- USP designation: L1 (C18).
Advantages:
- High pH stability (to pH 11.5) and extended lifetime for silica‑based C18 separations due to bidentate bonding and double endcapping.
- Improved peak shape, efficiency and resolution for basic compounds compared with conventional columns, enabling better quantitation.
- UHPLC performance (1.8 µm particles with 600 bar rating) suitable for fast, high‑definition separations and LC/MS workflows using high‑pH buffers for enhanced sensitivity.
