Demanding Über One Test Probe Mix for Consistent Column Inertness Performance

The Ultra Inert GC columns set the new industry standards for consistent column inertness and exceptionally low column bleed. These columns allow you to perform trace level analysis – including the analysis of acids, bases, and other active compounds – with the utmost confidence. They help ensure an inert GC flow path which is essential for sensitivity, performance, and the integrity of your results. The columns can be routinely used for applications in the environmental, forensics, foods/flavors/fragrances, pharmaceutical, and special chemical industries.

The analysis of trace level samples and active compounds requires the most inert columns available. To meet the rigorous requirements that modern applications demand, a new Über One test probe mix is adopted for testing each ultra inert column individually. The carefully selected chemical species known to adsorb onto active surfaces provide an in-depth evaluation of column inertness.

This new testing procedure is built on the already tightest industry QC specifications for bleed, sensitivity, and efficiency. It goes a long way in assuring a successful analysis for challenging analytes, providing you the most consistent column inertness performance.

Features of J&W Ultra Inert GC Columns

Maximum reproducibility. Every Agilent J&W Ultra Inert and GC/MS columns are individually tested for low column bleed, consistent selectivity, accurate column dimensions, superior inertness, and high efficiency – the proof is the Performance Summary Sheet shipped with every column. You can be sure of minimal method adjustment when changing columns.

Better precision and reliability. All columns must adhere to tight retention factor (k) specifications and narrow retention indexes to ensure reproducible peak separation from column to column.

More accurate quantification. A high number of theoretical plates per meter promotes narrow peaks and improves the resolution of closely eluting peaks.

Improved signal-to-noise ratios. We are constantly developing new ways to reduce column bleed and activity, so you can minimize background noise and maximize sensitivity.

Better peak shape for challenging active compounds. We measure peak height ratios or peak tailing factors for active compounds such as acids and bases to ensure excellent peak shape for a broad range of difficult-to-chromatograph compounds.
