low-polarity phase Crossbond diphenyl dimethyl polysiloxane The diphenyl dimethyl polysiloxane stationary phase is the most popular GC stationary phase and is used in a wide variety of applications. All residual catalysts and low molecular weight

midpolarity phase Crossbond phenyl methyl polysiloxane The high thermal stability of Rtx-50 columns makes dual-column analysis possible with common phases such as Rtx-1 or Rtx-5MS. General-purpose columns for pesticides, herbicides, rosin acids,

proprietary Crossbond phase These columns separate to baseline all blood alcohol compounds in blood, breath, or urine, in less than 3 minutes, under isothermal conditions. Isothermal analysis increases productivity by eliminating the need for oven

Column bleed, measured by ECD, is extremely low at temperatures up to 330&degC, which is critical for baking-out the column to remove high-boiling compounds commonly found in pesticide/PCB extracts. An analysis time of less than 10 minutes improves

proprietary Crossbond phase 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

Crossbond 100% dimethyl polysiloxane&mdashoptimized for hydrocarbon analysis Gasolines are complex mixtures of hundreds of compounds. Information about concentrations of the individual components is important for evaluating raw materials and for

proprietary Crossbond phase Unique polymer for PCBs analysis by GC-ECD or GC-MS. Good results for other semivolatiles. Low polarity inert to active compounds. Stable to 340&degC

proprietary Crossbond phase The Rtx-VRX stationary phase and optimized column dimensions provide low bleed, excellent resolution, and fast analysis times for volatile compounds. Application-specific columns for volatile organic pollutants.

midpolarity phase Crossbond diphenyl dimethyl polysiloxane Rxi fused silica capillary GC columns were designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In

nonpolar phase dimethyl polysiloxane Rxi fused silica capillary GC columns were designed specifically to be the best columns available, for exceptional inertness, ultra-low bleed, and reproducible retention and selectivity. In addition to

Ideal for the analysis of triglycerides in edible oils Excellent thermal stability up to 370 °C ensures consistent results and longer column lifetimes Separate and quantify critical triglycerides (acylglycerols) without interference from column

midpolarity proprietary phase 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
