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.
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.
Use the CS12A-5μm columns for high efficiency and fast analysis (4 min). The smaller-diameter resin technology and reduced column length provide faster analysis time, reduced eluent consumption, and increased sensitivity. The CS12A column is the recommended replacement for all CS12 applications. Use the CS12A column with the Eluent Generator for simplified methanesulfonic acid eluent preparation.
