The CS5A column, in combination with postcolumn derivitization and visible detection at 530 nm, provides a sensitive and selective method for transition metal analysis.Recommended for the separation of transition and lanthanide metalsAlso useful for aluminum analysisThe CS5A column provides simultaneous determination of common transition metals in less than 11 min using a unique bifunctional resin. The transition metals are detected following complexation with 4-(2-pyridylazo) resorcinol (PAR). The PAR derivative is detected at 520–530 nm. This method is both sensitive and selective for transition metals.The CS5A provides improved selectivity and higher efficiencies than its predecessor, the CS5 column. Use the MetPac PDCA and Oxalic Acid Eluent Concentrates and PAR Postcolumn Reagent Diluent for simplified operation.IonPac CS5A Cation-Exchange Column SpecificationsDimensionsIonPac CS5A Analytical Column:4 × 250 mm and 2 × 250 mmIonPac CG5A Guard Column:4 × 50 mm and 2 × 50 mmMaximum operating pressure2500 psi (17.3 MPa)Mobile phase compatibilityTypical HPLC solvents to 50%Substrate characteristicsBead Diameter: 9 μmBead Type: MicroBead™ latex, bilayer of anion-exchange and cation-exchangeCross-Linking (%DVB): 55%Anion exchangeLatex Diameter: 76 nmLatex Cross-Linking: 2%Capacity: 40 μeq/column (4 × 250 mm) 10 μeq/column (2 × 250 mm)Ion-Exchange Group: Quaternary ammoniumCation exchangeLatex Diameter: 140 nmLatex Cross-Linking: 10%Capacity: 20 μeq/column (4 × 250 mm) 5 μeq/column (2 × 250 mm)Ion-Exchange Group: Sulfonic acidColumn constructionPEEK™ with 10-32 threaded ferrule-style end fittings.All components are nonmetallic.订货信息:Analytical ColumnsIonPac CS5A Analytical Column (4 x 250 mm)046100IonPac CS5A Analytical Column (2 x 250 mm)052576Guard ColumnsIonPac CG5A Guard Column (4 x 50 mm)046104IonPac CG5A Guard Column (2 x 50 mm)052836应用谱图:
