Rtx-CLPesticides

• Application-specific columns for organochlorine pesticides and herbicides.
• Low bleed--ideal for GC/ECD or GC/MS analyses.
• Baseline separations in less than 10 minutes.

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.

Applications

• Organochlorine pesticides and herbicides

Rtx-5 PONA

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

• Application-specific for detailed hydrocarbon analysis.

Applications

• Detailed hydrocarbon analysis

Rt-CW20M F&F

(Carbowax® polyethylene glycol)

• Application-specific columns for flavor and fragrance compounds, specially tested. True non-bonded Carbowax® 20M polarity.

Applications

• Flavor and fragrance compounds

Rtx-Volatiles

(proprietary Crossbond® diphenyl/dimethyl polysiloxane phase )

• 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.
• Rtx®-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)
• Glycols
• Common industrial solvents

Rtx-BAC1

• Application-specific columns for blood alcohol analysis
• Rtx®-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)
• Glycols
• Common industrial solvents
• Explosives

Rtx-TNT 2

• Application-specific columns for explosives in US EPA Method 8095.
• Low 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.

Applications

• Explosives

Rtx-PCB

• Unique polymer for PCBs analysis by GC/ECD or GC/MS.
• Good results for other semivolatiles.
• Low polarity; inert to active compounds.

Applications

• PCBs

Rtx-502.2

(proprietary Crossbond® diphenyl/dimethyl polysiloxane phase)

• 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.

Applications

• Volatile organic pollutants
