Extend column lifetime. Excellent inertness—obtain lower detection limits for active compounds. Sharper chromatographic peaks by utilizing retention gap technology. Maximum temperature: 360 °C.

The Restek Cleaning Kit can be used with any injection port

Aroclor standards may exhibit lot-to-lot variation

3-IN-1 TECHNOLOGY with Rxi® columns: • Highest Inertness • Lowest Bleed • Exceptional ReproducibilityRxi® columns are more stable at high temperatures than any other manufacturer’s column, resulting in higher system sensitivity. This low-bleed characteristic is the result of superior stabilization achieved by optimizing polymer cross-linking and surface deactivation technologies. Benefits of using ultra-low bleed Rxi® column…

• 47 mm glass fiber disks embedded with styrene/DVB resin. • For chlorinated, benzidine-containing, or nitrogen-containing pesticides. • Meet requirements of EPA Methods 515.2 and 553.

This highly retentive, highly selective phase—unique to Restek—was developed specifically for the analysis of aldehydes and ketones as DNPH derivatives. Allure AK is a reversed-phase HPLC material that has the unique ability to separate all 13 carbonyl compounds specified in California Air Resources Board (CARB) Method #1004 using a simple acetonitrile/water gradient. Other columns require long analysis times or the use of tet…

Attach to the column in seconds to form an airtight seal. Increase column lifetime—prevent moisture and air from entering the column during storage. Two styles to choose from: glass or silicone material. Glass caps are color-coded for identifying detector and injector ends. Not recommended for reuse.

Reversible Flip Seal—Same Cost, Twice the Lifetime New reversible Flip Seal inlet seals from Restek last twice as long as other inlet seals. Simply use—flip—then use again. The reversible design doubles the number of analyses you get per seal. •Same easy sealing as Dual Vespel® Ring Inlet Seals—no extra washer needed. •Lower leak rate than OEM metal seals. •Maximum transfer of analytes to column, due to highly inert gold or Si…

• Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. • Stable response factors make this column ideal for process-type applications where recalibration must be minimized. • High loadability reduces peak tailing and improves separations. • Extended temperature range up to 250 °C for fast elution of high molecular weight (HMW) hydrocarbons and accelerated…

A revolutionary new version of Restek’s popular EZGC™ application is now live — it’s easier to use and it’s absolutely free. Just enter your compounds, and this cutting-edge system will recommend not only a GC column, but also the conditions to reliably separate your target analytes. It will even show you a modeled chromatogram! On a PC or Mac, desktop or tablet, the EZGC™ web app can go anywhere and will quickly become your g…
