With Raptor™ LC columns, Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. SPP core-shell columns commonly employ traditional phe…

A Restek® LC guard cartridge in an EXP® direct connect holder is the ultimate in column protection. To help protect your investment and further extend the life of our already-rugged LC columns, Restek offers the patent-pending guard column hardware developed by Optimize Technologies.Raptor™ EXP® Guard Column Cartridges Features: Free-Turn® architecture lets you change cartridges by hand without breaking inlet/outlet fluid…

Restek has raised the bar with a new high-temperature MXT®-Biodiesel TG column line to complement their fused silica column line for biodiesel analysis. These new MXT® -Biodiesel TG columns are stable to 430°C and offer unique retention gap options that minimize dead volume and leaks. Choose either a 0.32mm column factory-coupled to a 0.53mm retention gap, or select a single unit 0.53mm column featuring Integra-Gap™, a built-…

The Raptor™ ARC-18 column is made specifically for high-throughput, low–sample prep LC-MS/MS applications. A well-balanced retention profile offers better detection and integration of large, multiclass analyte lists, and steric protection helps this SPP column endure the harsh, low-pH mobile phases needed for mass spec without sacrificing retention or peak quality. Restek chemists became the first to combine the speed of supe…

Diluted and DEA-exempt—no need to purchase costly neat materials or make your own standards. Pair with Restek's THC standards to analyze both neutrals and acids in cannabis products by LC. A must for accurate quantification in medical cannabis potency testing and strain ID. Acetonitrile solvent helps maintain stability by preventing methylation of the carboxylic acid group on the molecule. Certified reference materia…

The Rxi®-PAH GC columns were designed by Restek with a higher phenyl-content stationary phase that provides unique selectivity to separate important polycyclic aromatic hydrocarbons (PAH) for food safety that cannot be distinguished by mass spectrometry. Even difficult priority compounds, such as the European Food Safety Authority (EFSA) PAH4, are easily separated and accurately quantified, results that cannot be achieved on…

Improved resolution and faster analyses, compared to 1701 or phenyl phases, make these the pesticide columns of choice. Rtx®-CLPesticides columns are specially designed to overcome the coelutions and analyte breakdown typically encountered in chlorinated pesticide analyses for EPA Methods 8081, 608, and CLP. By achieving baseline resolution of the 20 target analytes, more accurate qualitative data can be obtained, providing r…

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. Every LC lab has a cache of C18s, but every C18 is not created equal. Because t…

For ultimate inertness, SilcoCan® air sampling canisters feature our unique Siltek® treatment technology. Even highly active components, at low parts-per-billion concentrations, can be readily sampled and stored without loss. The RAVE™ valve is a high-quality, metal-to-metal seal, 2/3-turn valve with metal diaphragms to prevent sample adsorption for more-accurate results. Both stainless steel and Siltek®-treated RAVE™ valves…

midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane

Force LC columns are available with Restek's most popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.

Force LC columns are available with Restek's most popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.

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…
