Traces of water in the carrier
gas and sampleswill affect
the retention and selectivity of
alumina. If exposed towater,
the retention timeswill short-
en.The column can be regen-
erated by conditioning for 15-
30min. at 200°C under normal
carrier gas flow. Periodic con-
ditioning ensures excellent
run-to-run retention time
reproducibility.
Themaximum programmable
temperature for an
Rt
®
-AluminaBOND column is
200°C. Higher temperatures
cause irreversible changes to
the porous layer adsorption
properties.

Rt®-AluminaBONDColumns
• Applications forC1-C10 volatile hydrocarbon separations at percent levels, aswell as impurity
analyses at ppm concentrations.
• High capacity and loadability give exceptionally symmetric peaks.
• Reproducible retention times andpredictable flowbehavior column-to-column.

• Acetylene/propadiene elute after butanes (impurities in acetylene/propadiene).
• Best separation for butene isomers (impurities inbutene streams).
• Methyl acetylene elutes after 1,3-butadiene.
• Cyclopropane (impurity inpropylene) eluteswell before propylene.

• Acetylene elutes beforeC4hydrocarbons (impurities inbutane/isobutane).
• Methyl acetylene (impurity in1,3-butadiene) elutes before 1,3-butadiene.
