        Stx-CLPesticides2

        • Application-specific columns for organochlorine pesticides and herbicides .
        • GC columnSiltek® surface deactivation enhances responses for endrin, DDT, methoxychlor.

        Many laboratories analyzing organochlorine pesticides struggle with breakdown and adsorption of endrin, DDT, and methoxychlor caused by active sites throughout the analytical system. Siltek® passivation technology enables these columns to offer unsurpassed inertness and the highest responses for active pesticides.

        Rtx-CLPesticides2

        • Application-specific columns for organochlorine pesticides and herbicides.
        • GC columnLow bleed--ideal for GC/ECD or GC/MS analyses.
        • 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 reliable identification without GC/MS.

        Column bleed, measured by ECD, is extremely low at temperatures up to 330°C, 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 throughput compared to other stationary phases. Baseline separations in less than 10 minutes.

        Rtx-Volatiles

        (proprietary Crossbond® diphenyl/dimethyl polysiloxane phase )GC column

        • Application-specific columns for volatile organic pollutants.

        Rtx®-Volatiles columns were the first columns designed specifically for analyses of the 34 volatile organic pollutants listed in US EPA methods 601, 602, and 624. With these columns, you can quantify all compounds listed in these methods, whether you use a mass spectrometer or a PID in tandem with an ELCD. The diphenyl/dimethyl polysiloxane based Rtx®-Volatiles stationary phase provides low bleed and thermal stability to 280°C. Narrow bore columns can interface directly in GC/MS systems.

        Rtx-BAC2

        • Application-specific columns for blood alcohol analysis.
        • GC columnRtx®-BAC2 confirmation column provides four elution order changes under the same conditions

        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 cycling. Confirmation is easily achieved with this tandem set because there are four elution order changes between the two columns.

        Applications
        • Blood alcohol analysis
        • Abused inhalant anesthetics
        • y-hydroxybutyrate (GHB)/y-butyrolactone (GBL)

        Rtx-TNT 2

        • Application-specific columns for explosives in US EPA Method 8095.
        • GC columnLow bleed--ideal for ECD analysis.
        • Complete analysis in less than 20 minutes.
        • Rtx®-TNT2 confirmation column provides 8 elution order changes under same conditions.

        We designed Rtx®-TNT and Rtx®-TNT2 columns specifically for analyses of nitroaromatic compounds by GC/ECD, such as the 16 analytes listed in US EPA Method 8095. They provide better resolution and higher thermal stability than any other currently recommended columns. Operate the Rtx®-TNT primary column and Rtx®-TNT2 confirmation column under identical GC oven temperature programs.
