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…

MXT® columns are made from stainless steel tubing that has had the internal surface treated with our exclusive Siltek® surface treatment. The Siltek® layer makes the surface as inert as deactivated fused silica. The unique properties of the Siltek® treated surface enable us to treat the tubing with a wide variety of polymer phases.MXT®-WAX Columns Features: General-purpose columns for FAMEs, flavor compounds, essential oi…

Restek’s Rt®-Silica BOND columns are robust, versatile, selective PLOT columns that offer excellent performance for the analysis of light hydrocarbons, sulfur gases, and halocarbons above ambient temperature. In addition, carbon dioxide and other gases can be retained at ambient temperature on this silica-based column. High loadability, inertness, and consistent selectivity, as well as unmatched robustness at a maximum temper…
