The Rtx-65 phase contains the high phenyl content 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. 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.
  • Mid- to high-polarity phase
  • Crossbond™ diphenyl dimethyl polysiloxane
  • Confirmation column for EPA Method 604 phenols
  • Produces a different elution order compared to the primary Rtx-5 column
  • Temperature Range: 50° to 300°C
