GC COLUMNS | GENERAL-PURPOSE COLUMNS
Rtx®-50, Rtx®-65
Rtx®-50 Columns (fused silica)
(midpolarity phase; Crossbond® phenyl methyl polysiloxane)
• General-purpose columns for pesticides, herbicides, rosin acids, phthalate esters,
sterols.
• Temperature range: 40 °C to 320 °C.
• Equivalent to USP G3 phase.
The high thermal stability of Rtx®-50 columns makes dual-column analysis possible
with common phases such as Rtx®-1 or Rtx®-5MS.

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.
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 vari-
ety 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.
