Rt®-AluminaBOND/CFCColumns
(fusedsilicaPLOT)
• Improved inertness for halogenated compounds.
• Highly selective alumina-based column, separatesmostCFCs.
• High retention and capacity forCFCs.
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/CFCcolumn is thoroughlydeactivated to reduce the reactivityof alumina.Even
though there is still some residual reactivity for some mono- or di-substituted halo-
genated hydrocarbons, themajority of these compounds can be accurately quantified
frommain streamprocesses or in impurity analyses.
