No active sites after long use, this liner is wonderful
Rating: 5.0

  • Application Area:EPA methods 524.2, 515.4, and 525.2

"These liners were a life saver for me. I don't run many injections and having to replace the liner every time, because they develop an active site, was costly and time consuming. Thanks to a very helpful rep. I was able to sample several different liner configurations and I chose the best one for each of my methods. Now I am able to run for six weeks without having to replace the liner and still have my breakdown check for 525.2 pass every time. I have recommended them to other people in my area and to those I meet when going to conferences out of state."

Rating: 5.0

  • Application Area:Analyze food products for a variety of tests but primarily FAME analysis

"Excellent liner for variety of testing on GC and GC/MS applications - I have used Restek liners for many years and have always been pleased with how robust they are with repeatable results. I have used them for testing pesticides and very pleased with stability and lack of breakdown in compounds. Packaging is convenient (I buy 5 packs) and have never received late orders of broken liners."

Lowest breakdown I've seen. Somehow they've beaten the Skyliners' greatness.
Rating: 5.0

  • Application Area:Chlorinated Pesticides via EPA 8081

"I replaced the old Skyliner PTV liner with the new Topaz PTV liner, and performed a quick "bake-out". Instantly the chromatograms looked clean and the breakdown was well below 5% for Endrin and DDT. When you only get up to 15%, any wiggle room will help. If a consumable can reduce reruns, we can maximize efficiency and turn-around-times. Thanks for your innovation. For a high-volume throughput lab it greatly eases my stress."

Rating: 3.7

"The liners are overall really good. We usually get very uniform and reproducible results and installation is quick and easy. From time to time we will run into an abnormality and it does take some time for somebody to get back to us. For the amount of product we use I feel we should be able to get a better price."

Rating: 5.0

  • Application Area:Reading Antigen Antibody Reactions

"A must have if you own a Topaz equipment. The inlet liners keep the inlet lines straight and durable. No longer do I worry about kinks and inlets being removed for any number of reasons! We had a faulty inlet liner before, but customer service replaced it right away even though it was a back-up liner that we had in storage."
