This document describes the features and characteristics of Agilent J&W columns, including reducing background noise, minimizing chemically active residues, and improving sensitivity. The Ultra Inert capillary columns in this series have maximum inertness and low carryover, which can enhance the signal-to-noise ratio and sensitivity.
This document introduces the Agilent J&W Ultra Inert capillary columns designed for Gas Chromatography (GC) and GC/MS applications. These columns feature maximum chemical inertness and low bleed, even at high temperatures, which improves the signal-to-noise ratio and sensitivity for difficult analytes. The text explains that these columns utilize special surface deactivation chemistries and siloxane phases to prevent analyte adsorption on active sites, ensuring reliable results without the need to revalidate methods. This manual is written in French.
| Chemical Inertness | Maximum chemical inertness |
|---|---|
| Bleed Level | Low bleed |
| Phase Composition | 100% diméthylpolysiloxane |
No, they do not require revalidation because they maintain the same selectivity as standard MS columns.
They allow achieving the lowest possible detection limits for difficult analytes due to maximum inertness and low bleed.
