Rt®-Alumina BOND/CFC Columns
(fused silica PLOT)
• Improved inertness for halogenated compounds.
• Highly selective alumina-based column, separates most CFCs.
• High retention and capacity for CFCs.
The alumina adsorbent is ideal for retaining halogenated compounds, especially CFC
(chlorinated flourocarbons, freons). It offers high selectivity, allowing a wide range of
CFC isomers to be resolved at above ambient temperatures. 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 halo-
genated hydrocarbons, the majority of these compounds can be accurately quantified
from main stream processes or in impurity analyses.
