mid- to high-polarity phase; Crossbond diphenyl dimethyl polysiloxane
The Rtx-65 phase contains the highest phenyl content of any bonded stationary phase available to improve separation of aromatic compounds through increased phase-analyte 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. Rtx-65 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.
- General-purpose columns for phenols, fatty acids, triglycerides
- Temperature range: 50°C to 300°C
