GC COLUMNS | APPLICATION-SPECIFIC COLUMNSPetroleum & PetrochemicalNEW!Chlorinated Fluorocarbons (CFC) AnalysisRt®-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 ofCFC isomers to be resolved at above ambient temperatures. The Rt®-AluminaBOND/CFC column is thoroughly deactivated to reduce the reactivity of alumina. Eventhough there is still some residual reactivity for some mono- or di-substituted halogenatedhydrocarbons, the majority of these compounds can be accurately quantifiedfrom main stream processes or in impurity analyses.ID df temp. limits 30-Meter0.53mm 10µm to 200°C 19763Impurity analysis of 1,1,2,2-tetrafluoroethane (CFC-134a) on an Rt®-Alumina BOND/CFC column.Rt®-Alumina BOND/CFC columnsprovide the best selectivity forimpurity analysis of CFCs.4Peaks1.
