        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.

        Applications
        • Volatile organic pollutants

        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.

        Rtx-502.2

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

        • Application-specific columns with unique selectivity for volatile organic pollutants. The Rtx®-502.2 column is cited in US EPA Method 502.2 and in many gasoline range organics (GRO) methods for monitoring underground storage tanks.
        • Excellent separation of trihalomethanes; ideal polarity for light hydrocarbons and aromatics.

        An Rtx®-502.2 column will enable you to quantify all compounds listed in US EPA methods 502.2 or 524.2, whether you use a mass spectrometer or a PID in tandem with an ELCD. The diphenyl/dimethyl polysiloxane based Rtx®-502.2 stationary phase provides low bleed and thermal stability to 270°C. A 105-meter column can separate the light gases specified in EPA methods without subambient cooling. Narrow bore columns can interface directly in GC/MS systems.

        Rtx-5 Amine

        (Crossbond® 5% diphenyl/95% dimethyl polysiloxane)GC column

        • Application-specific columns for amines and other basic compounds.
        • Low polarity phase.

        Active basic compounds that otherwise require derivatization, or an alternative analytical technique, can be analyzed on an Rtx®-5 Amine column. The tubing surface is chemically altered to reduce tailing of basic compounds, eliminating the need for column priming. An Rtx®-5 Amine column is ideal for analyzing a wide variety of basic compounds, but breakthrough technology also allows the analysis of neutral compounds, adsorptive compounds with oxygen groups susceptible to hydrogen bonding, or even weakly acidic compounds such as phenols. Every Rtx®-5 Amine column is tested to ensure that it exceeds the requirements for analyzing ppm levels of amines, without priming, and to ensure low bleed at maximum operating temperature.

        Applications
        • Alkylamines
        • Diamines
        • Triamines
        • Ethanolamines
        • Nitrogen-containing heterocyclics
