Optimized column selectivities guarantee resolution of ethanol, internal standards, and frequently encountered interferences. Robust and reproducible column chemistry ensures longer column lifetime and consistent results. 2 minute analysis time increases lab productivity. Stable to 260 °C Don’t forget: Blood alcohol analysis requires dual column confirmation when using GC/FID.

•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.

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!

Rtx®-VMS Columns (fused silica) (proprietary Crossbond® phase) • Application-specific columns for volatile organic pollutants by GC-MS • Complete separation of U.S. EPA Method 8260B compounds in less than 10 minutes • Stable to 260 °C • No known equivalent phases

Developed specifically for using LC coupled with GC-FID to accurately determine hydrocarbons found in mineral oils, which can migrate from packaging into food. • 9-component mix contains non-interfering internal standards as well as both mineral oil saturated hydrocarbon (MOSH) and mineral oil aromatic hydrocarbon (MOAH) markers to correctly cut fractions. • Certified reference material (CRM) manufactured and QC-tested in Re…

The Rtx®-Volatile Amine column was designed specifically for analyzing volatile amines in difficult matrices, such as water. The unique base deactivation creates an exceptionally inert surface for these sensitive compounds, resulting in highly symmetrical peaks which allow low detection limits. The stable bonded phase yields a column that is not only retentive and highly selective for these compounds, but is also very robust…

A Restek® LC guard cartridge in an EXP® direct connect holder is the ultimate in column protection.

Accurate boiling point determination for medium and heavy fractions using GC simulated distillation requires columns and phase polymers that are robust enough to withstand high temperatures without significant degradation.

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.

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.

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.

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.

Don't let a small leak turn into a costly repair—protect your analytical column by using a Restek leak detector. Audible tone indicates the severity of a leak. Redesigned circuitry offers 12 hours of operation between charges. Detects a broad range of gases; Ex rated for use with hydrogen and other explosive gases.

Restek offers a full range of porous polymers, including HayeSep and Porapak polymer packings for analyses of volatile compounds and light solvents.

Removes up to 135 ml of oxygen or 2 g of water.
