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. For separation of trihalomethanes, ideal polarity for light hydrocarbons and aromatics.

Supplier: Restek

Ultra IBD is a polar-embedded column that acts as a strong hydrogen bonder. With a unique polar group this column is very retentive and selective for acids. It also provides symmetrical peak shape for strong bases. This columns are compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

Supplier: Thermo Fisher Scientific
