Rtx®-1 columns exhibit long lifetime and very low bleed at high operating temperatures. A proprietary synthesis process eliminates residual catalysts that could cause degradation and increase bleed.

• Wide range of stationary phases offers orthogonal separations. • High thermal stability maximizes system ruggedness and sensitivity. • Unrivaled column inertness for accurate analysis of active compounds. • 0.15, 0.18, and 0.25 mm ID formats accommodate varying sample capacities, speeds, and detectors. • Secondary columns come in convenient 2 m lengths for economical method development. GCxGC is a powerful multidimensional G…

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.

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…

Stop spending your time and money developing LC-MS/MS multi-residue pesticide methods and mixing reference standards when you could be running samples. Restek’s trusted food safety experts have already done the work for you—with guaranteed accuracy and at a lower cost.

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.

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.

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.

midpolarity phase; Crossbond® trifluoropropylmethyl polysiloxane

Deactivation - unbelievably low breakdown for accurate and precise low-level GC analyses.

Low-polarity phase; Crossbond diphenyl dimethyl polysiloxane

Pro EZGC Chromatogram Modeler Propels Method Development Forward

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.

Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind.

For Agilent GCs equipped with split/splitless inlets

Midpolarity crossbond phase general-purpose columns for alcohols, oxygenates, PCB congeners (e.g., Aroclor mixes), pesticides, and fragrance compounds. Equivalent to USP G46 phase.

A low- to midpolarity phase application-specific columns for volatile organic pollutants. Recommended in U.S. EPA methods for volatile organic pollutants. Temperature range: -20 °C to 240 °C. Equivalent to USP G43 phase. The unique polarity of the Rtx-624 column makes it ideal for analyzing volatile organic pollutants. Although the Rtx-502.2 column is recommended in many methods, the Rtx-624 column offers better resolution…
