Agilent J&W CP-Wax 57 CB for Glycols and Alcohols is optimized for the analysis of glycols, diols and alcohols. It has a unique, high polarity wax phase that produces symmetrical peaks. The cross-linked and bonded phase delivers robustness and enhanced column lifetime.

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. 

The GS-OxyPLOT column provides the ultimate solution for the chemical and petrochemical industries to analyze trace levels of oxygenates in complex matrices such as gaseous hydrocarbons, motor fuels, and crude oil.

Mid-Polar UI column; a great choice for drugs of abuse testing and pesticides analysis. Agilent J&W continues their ultra inert innovations with the DB-35ms Ultra Inert GC column; a mid-polar column joining the existing apolar columns in the family, DB/HP-1ms and DB/HP-5ms.  With this new column, ultra inert performance is available for applications where different selectivity is needed for enhanced separations, including pest…

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.

•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.

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…

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.
