This document introduces Agilent's ZORBAX Eclipse XDB HPLC columns, which show excellent peak shape for basic compounds in the pH range of 6-9 and also perform outstandingly at low pH.
The leaflet introduces the ZORBAX Eclipse XDB column family, highlighting the eXtra Dense Bonding (XDB) technology, double endcapping, and the use of hard‑wall sol‑gel silica that provides excellent peak shape and long column life across a wide pH range.
It also lists detailed column specifications, available bonded phases (C18, C8, Phenyl), particle sizes, dimensions, and ordering part numbers, along with purge and test conditions for performance evaluation.
| Endcapped | Double |
|---|---|
| Particle Size | 5 µm and 3.5 µm |
| Column Dimensions (Standard) | 4.6 × 150 mm |
| Maximum Operating Pressure | 5000 psi (regular use) |
Eclipse XDB columns are offered with 5 µm and 3.5 µm particle sizes.
The columns are packed at pressures exceeding 8000 psi and can tolerate up to 5000 psi in regular use without loss of efficiency.
