Agilent J&W DB-1ms and HP-1ms Ultra Inert Capillary GC Columns
The Ultra Inert 1ms 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.
Demanding Ultra Inert 1ms Test Probe Mixture for Consistent Column Inertness Performance
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 Ultra Inert 1ms test probe mixture is adopted for testing each Ultra Inert 1ms 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.

Highest Degree of Column Inertness and Exceptional Low Column Bleed
Considered separately, neither low bleed nor low activity individually confers a significant advantage to trace analysis. Low bleed increases the signal-to-noise ratio, but if any of the analyte is adsorbed by active sites in the column, the results are flawed. Similarly, if the column is well deactivated but the bleed rate is high, some of the signal generated by the analyte is smothered by the bleed signal. Again, the results are flawed. Only when the column exhibits both low bleed and low activity are the results reliable.
Agilent J&W Ultra Inert columns are the only GC columns proven to deliver on the promise of consistent column inertness and exceptionally low column bleed.
