Fused Silica Alumina BOND Columns
Rt®-Alumina BOND/CFC Columns
(fused silica PLOT)
• Improved inertness for chlorofluorocarbon (CFC) compounds.
• Highly selective alumina-based column, separates most CFCs.
• High retention and capacity for CFCs.
• Stable to 200 °C.
The Alumina BOND/CFC adsorbent is ideal for retaining halogenated compounds,
especially CFCs (chlorinated fluorocarbons) like Freon® products. It offers high selec-
tivity, allowing a wide range of CFC isomers to be resolved at above ambient tempera-
tures. The Rt®-Alumina BOND/CFC column is thoroughly deactivated to reduce the
reactivity of alumina. Even though there is still some residual reactivity for some
mono- or di-substituted CFCs, the majority of these compounds can be accurately
quantified from main stream processes or in impurity analyses.
