Patented Topaz GC inlet liners feature revolutionary technology and inertness to deliver the next level of True Blue Performance:

  • Deactivation—unbelievably low breakdown for accurate and precise low-level GC analyses.
  • Reproducibility—unbeatable manufacturing controls and QC testing for superior reliability across compound classes.
  • Productivity—unparalleled cleanliness for maximized GC uptime and lab throughput.
 

The Next Level of True Blue Deactivation

As the demand for lower detection limits continues to grow, even the smallest amount of activity in your liner can cause analyte breakdown and impact your results—tailing peaks, loss of response, and other issues we’ve all experienced. In developing Topaz GC inlet liners, our chemists created a new deactivation that yields unbelievably low breakdown.

Liner inertness can be described as the reduction in unwanted reactions between a liner and active compounds (and, therefore, a reduction in analyte breakdown and adsorption). Topaz deactivation technology thoroughly passivates the liner—and the wool inside—so that your liner is highly inert to a wide array of reactive analytes. This inertness increases peak symmetry and response, leading to better quantitation, accuracy, and precision.

With deactivated Topaz liners, you prevent unwanted chemical interactions and minimize breakdown, which improves your data quality and dependability and reduces instrument downtime. Even for low-level GC analysis of highly sensitive compounds—like 2,4-DNP, carbaryl, endrin, and DDT—these highly inert liners provide high-quality results that you’ll have to see for yourself to believe.

Figure 1: High inertness is important, especially when using wool. Comparatively testing liners using highly reactive 2,4-DNP shows the competition simply can’t compete.

Perfect Installation Every Time

There is never a question about which way to install a Topaz liner—simply orient it so that the column installs towards the "R" in the Restek logo.

 

The Next Level of True Blue Productivity

Any time spent with your instrument offline—such as when changing your GC inlet liner or conditioning it afterward—directly ties to increased cost per analysis and decreased revenue for your lab and raises the odds of yet another evening at the bench catching up on backlogged work for you. Whether you’re standing in Restek’s applications lab or at your own bench, it is imperative to keep running samples as long as possible, and when you do need to perform maintenance, to get back up and running as quickly as possible.

With the stability and inertness of a Topaz liner, you can analyze more samples before your data quality declines and you have to stop to replace your liner.

Figure 5: The stability of a Topaz liner shines compared to leading competitors. Breakdown of a reactive compound like endrin starts low and stays low, even after 40 injections.

See Figure 3 for conditions.

Superior Cleanliness for Maximum Uptime

Topaz liners also feature blister packaging developed for superior cleanliness. The cleaner the liner, the less time you spend conditioning after changing your liner. Greater instrument uptime translates into more samples run and more profit for your lab. Get it with the unparalleled stability and cleanliness of Topaz inlet liners.
