GC Columns Products & Reviews

The Select FAME column is tuned for optimal cis/trans separations of FAMEs, especially the C18 isomers. The bonded column has an isothermal maximum operation temperature of 275°C and a programmed temperature of 290°C - a dramatic improvement of 50°C compared to non-bonded columns. Select FAME has better detection limits because the column has a very low bleed level. Even though this is a very polar column, the column efficienc…

Agilent J&W DB-FastFAME is a cyanopropyl phase engineered for the fast and selective separation of polysaturated and unsaturated FAMEs—even challenging cis and trans FAME isomers—without sacrificing the resolution generally achieved with traditional 100 meter long columns.

Agilent J&W DB-1ms is a nonpolar, low bleed column, with excellent inertness for acids and bases and an extended upper temperature limit. Using low bleed stationary phases in DB-1ms reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity. 

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. • General purpose columns for solvent impurities, PCB congeners (e.g. Aroclor mixes), simulated distillation, drugs of abuse, gases, natural gas odorants, sulfur compounds, essential oils, hydrocarbons, semivolatiles, pesticides,…

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

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…

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 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…
