This document introduces the features and characteristics of Agilent ZORBAX HPLC columns, including resolution, column life, and usage methods.
This document serves as a selection guide for Agilent ZORBAX columns designed for analytical HPLC applications. It details the unique ZORBAX Silica manufacturing process, specifically the Rx-SIL technology, which provides high purity, strength, and controlled pore size to ensure resolution that lasts. The guide explains how these silica characteristics improve chromatographic performance by reducing peak tailing and increasing column durability under high pressure.
| Silica Purity | 99.995% |
|---|---|
| Maximum Operating Pressure | 8000 psi |
| Column Bed Stability Pressure | 5000 psi |
| pH Range for StableBond | 1 - 6 |
| pH Range for Eclipse XDB | 2 - 9 |
| pH Range for Extend-C18 | up to pH 11.5 |
It provides ultra-pure particles with low metal content and low acidity, which reduces peak tailing and improves chromatographic results.
It uses bulky, patented silanes to sterically protect the siloxane bond, providing extraordinary chemical and temperature stability in the pH 1-6 range.
It incorporates a unique, patented bidentate silane combined with a double-endcapping process that protects the silica from dissolution at high pH.
