Rtx®-50Columns (fusedsilica)
(midpolarityphase; Crossbond® 50%phenyl/50%methyl polysiloxane)
• General purpose columns for pesticides, herbicides, rosin acids, phthalate esters,
triglycerides, sterols.
• Temperature range: 40 °C to320 °C.
• Equivalent toUSPG3phase.
The high thermal stability of Rtx®-50 columns makes possible dual-column analysis
with commonphases such asRtx®-1MSorRtx®-5MS. Between analyses, high temper-
atures canbeused todrive less volatile contaminants off of the column.

Rtx®-65Columns (fusedsilica)
(mid tohighpolarityphase; Crossbond®65%diphenyl/35%dimethyl polysiloxane)
• General purpose columns for phenols, fatty acids.
• Temperature range: 50 °C to300 °C.
• Equivalent toUSPG17phase.
TheRtx®-65phase contains thehighest phenyl content of anybonded stationaryphase
available, to improve separationof aromatic compounds through increasedphase-ana-
lyte interaction.Aunique polaritymakes these columns ideal for a variety of analyses,
from phenols to FAMEs. As a confirmation column for EPAMethod 604 phenols, an
Rtx®-65 column produces a different elution order, compared to the primary Rtx®-5
column.Rtx®-65 columns eluteFAMEs according to equivalent chain length, similar to
bondedCarbowax® columns, but theRtx®-65phasedoes not suffer the thermal stabil-
ity limitations of other polar stationaryphases.
