The IonPac® CS12A is a medium-capacity, carboxylate-functionalized cation-exchange column recommended for fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices.

The new CS12A-8µm and CS12A-5µm Capillary Columns offer the same selectivity as their analytical-scale counterparts, but offer the advantage of reduced eluent consumption, thereby lowering operating costs.  

• Robust, reliable column for separation of group I and II cations plus ammonium
• Recommended for separation of manganese and morpholine
• Recommended for analyses of inorganic cations in complex matrices
• Simplified Reagent-Free IC operation provided by the EG or eluent regeneration
• Compatible with organic solvents (except alcohols), high temperatures, and high acid concentrations
• Analysis time for six common cations as short as 4 min (CS12A-5μm) to 15 min (CS12A-8μm)
• The CS12A-MS column offers fast elution at the low flow rates required for IC-MS, making it ideal for IC-MS screening
• For disparate concentration ratios of adjacent-eluting cations, the high-capacity IonPac CS16 is recommended

The medium-capacity IonPac CS12A cation-exchange column supports fast, isocratic separation with suppressed conductivity detection. Sample matrices include environmental and drinking waters; soil extracts; acid digests; power plant waters treated with ammonium or morpholine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents.
