Topaz Inlet Liners
100% Satisfaction—if your Topaz GC inlet liner doesn't perform
to your expectations, we will replace it or credit your account.
All Topaz inlet liners are produced with proprietary Restek processes and apply some of the tightest testing specifications in the industry. The exceptionally inert Topaz liners analysts want most are in stock now and are guaranteed to deliver outstanding performance that exceeds your expectations.

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


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

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

With deactivated Topaz GC inlet liners, you prevent unwanted chemical interactions and minimize breakdown, which improves your data quality and dependability and reduces instrument downtime. Even for extremely 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.

New Topaz GC inlet liners are made under strict manufacturing controls, followed by a battery of industry-specific QC tests, to prove that every lot we produce maintains superior reliability and outstanding inertness across a broad range of compound classes. By ensuring the utmost reproducibility in our liners, we help eliminate frustration and uncertainty in your work.

Figure 2: As shown with the low breakdown of notoriously reactive compounds like endrin and DDT, you can expect the same great results from one lot to the next with Topaz GC inlet liners.

In the end, we don’t test Topaz inlet liners to exceed method requirements. We don’t test Topaz liners to exceed industry norms. We manufacture and QC test Topaz liners to exceed your expectations and bring you the peace of mind that you can always depend on the quality and consistency of your data.

Any time spent with your instrument offline—like 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. 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 GC inlet liner, you can analyze more samples before your data quality declines and you have to stop to replace your liner.

Figure 3: 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.


Topaz inlet liners also feature blister packaging developed for superior cleanliness. The cleaner the liner, the less time you spend conditioning after a maintenance changeout.

Greater instrument uptime translates into more samples being run and more profit for your lab. Get it all with the unparalleled stability and cleanliness of Topaz inlet liners.

Warm Up Before You Run - Why conditioning your inlet parts after maintenance is good practice

Background noise in a gas chromatography system can be eliminated by conditioning the system prior to sample analysis. In this article, we discuss warm-up procedures and use liners and liner installation to demonstrate the importance of conditioning the system to remove background peaks. Investing a little time in warming-up the system pays big dividends by preventing costly coelutions and avoidable reanalyses.
