Great results and lifespan with the Force Columns
Application Area:Analyzing drugs in urine screens
"We love these columns! We updated our method in 2018 and switched from the Raptors to the Force columns and they are wonderful with what we use them for. Their life span has doubled if not tripled and they're a little cheaper than the Raptors. We still use the Raptors for our Oral Fluid method and they run great, but the Force is awesome! We get great results too."

Good unique column
Application Area:Reaction monitoring and GLP analyses
"Good unique column but bleeds a little. Takes a while to equilibrate. Wish it was also available in flash cartridges."

Great separation and stability and lifetime
Application Area:pesticides in foodstuff
"I am appreciative of RESTEK's after-sales care. They sent me the adult chromatogram and separation condition details. We didn’t need to find other ways to complete our method development. Also, this column's stability and lifetime was impressive. Thanks, Tom."
The culmination of 20+ years in LC, Force performance LC columns are long-lasting and reproducible, even under the stress of UHPLC.
Premium quality is backed by the strength of our 100% Pure Satisfaction guarantee. And perhaps most important, Force columns are fully scalable between 3 or 5 μm HPLC and 1.8 μm UHPLC, so you can easily transfer and optimize methods without extensive calculations.
Force FluoroPhenyl LC Columns (USP L43)
Restek's FluoroPhenyl phase offers chromatographers the ability to run in reversed-phase or HILIC mode for a variety of compounds. Restek's FluoroPhenyl columns are also amenable to LC-MS because they are extremely reliable and efficient with acidic mobile phases.
Force C18 LC Columns (USP L1)
The general-purpose Restek C18 is a conventional monomeric octadecylsilane column suitable for analyses of a wide range of compounds from acidic through slightly basic.
Force Biphenyl LC Columns (USP L11)
The innovative Biphenyl is Restek's most popular LC stationary phase because it is particularly adept at separating compounds that are hard to resolve or that elute early on C18 and other phenyl chemistries. As a result, Biphenyl columns are extremely useful for bioanalytical testing applications like drug and metabolite analyses, especially those that require a mass spectrometer (MS).
