Rtx®-502.2 Columns (fused silica)
(proprietary Crossbond® diphenyl/dimethyl polysiloxane phase)
• Application-specific columns with unique selectivity for volatile organic pollutants.
The Rtx®-502.2 column is cited in U.S. 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.
• Stable to 270 °C.
An Rtx®-502.2 column will enable you to quantify all compounds listed in U.S. 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®-Volatiles Columns (fused silica)
(proprietary Crossbond® diphenyl/dimethyl polysiloxane phase)
• Application-specific columns for volatile organic pollutants.
• Stable to 280 °C.
Rtx®-Volatiles columns were the first columns designed specifically for analyses of the
34 volatile organic pollutants listed in U.S. 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 polysi-
loxane based Rtx®-Volatiles stationary phase provides low bleed and thermal stability
to 280 °C. Narrow bore columns can interface directly in GC/MS systems.
