Thermo Scientific Dionex IonPac CS12A IC Columns

Separate common cations in as little as four minutes using methanesulfonic acid (MSA) or sulfuric acid eluents with Thermo Scientific™ Dionex™ IonPac™ CS12A Cation-Exchange Columns. These medium-capacity, carboxylate-functionalized cation-exchange columns are recommended for fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium in diverse sample matrices. The IonPac CS12A column is the recommended replacement for all IonPac CS12 column applications.

Analysis of Common Cations plus Ammonium in Diverse Sample Matrices

• Superior fast isocratic separation of mono- and divalent cations plus ammonium in diverse, complex matrices
• Isocratic separation of Group I and II cations plus ammonium in 15 minutes in diverse matrices using a 250mm column
• Fast, high resolution, isocratic separation of Group I and II cations plus ammonium in 4 minutes in simple matrices using 150mm column
• Higher-capacity applications use 250mm columns, allowing injection of more concentrated samples without overloading or peak broadening
• High efficiency, fast analysis use the 150mm column for increased sample throughput
• Dionex IonPac CS12A-MS column provides fast elution at the low flow rates required for IC-MS, making it the ideal choice for IC-MS screening
• Compatible with organic solvents, excluding alcohols, to enhance analyte solubility, modify column selectivity or allow effective column cleanup

The Dionex IonPac CS12A-8μm and CS12A-5μm Capillary Columns offer the same selectivity as their analytical-scale counterparts with lowering operating costs.

Recommended for Common Cations and Ammonium in Diverse Sample Matrices

• Source water and drinking water, municipal and industrial wastewater, soil extracts, acid digests
• Industrial cooling water, scrubber solutions; plating baths; and industrial solvents
• Power plant waters treated with ammonium or morpholine; chemical additives; chemical process solutions

Reduce Operating Costs With Lower Eluent Requirements

The Dionex IonPac CS12A capillary columns provide the same performance as the standard bore and microbore Dionex IonPac CS12A columns because they are packed with the same material. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system, requiring less eluent and producing less waste.

Multiple Formats Available for Application Flexibility

• 4x250mm, 2x250mm, 3x150mm or 2x100mm analytical columns
• 4x50mm or 2x50mm, 3x30mm guard columns
• 0.4x250mm, 0.4x150mm capillary columns
• 0.4x50mm or 0.4x35mm capillary guard columns
• Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
• Shorter 150mm and 100mm columns produce faster runs of relatively clean matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
