Mid-to high-polarity phase, Crossbond® diphenyl dimethyl polysiloxane, general-purpose columns for phenols, fatty acids, triglycerides.

• Temperature range from 50 to 300 °C
• Equivalent to USP G17 phase
• More thermo stabile

The Rtx®-65 phase contains the highest phenyl content of any bonded stationary phase available to improve separation of aromatic compounds through increased phaseanalyte interaction. A unique polarity makes these columns ideal for a variety of analyses, from phenols to FAMEs.

As a confirmation column for EPA Method 604 phenols, an Rtx®-65 column produces a different elution order compared to the primary Rtx®-5 column. These columns elute FAMEs according to equivalent chain length, similar to bonded Carbowax® columns, but the Rtx®-65 phase does not suffer the thermal stability limitations of other polar stationary phases.
