GC Capillary Column Rtx-65, 30 m, 0.32 mm ID, 0.50 µm

Rtx®-65 Columns (fused silica)

(mid to high polarity phase, Crossbond® diphenyl dimethyl polysiloxane)

• General-purpose columns for phenols, fatty acids, triglycerides.
• Temperature range: 50 °C to 300 °C.
• Equivalent to USP G17 phase.

Similar Phase(s): 007-65HT

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.
