Medium Capacity Column for Fast, Isocratic Separation of Cations Using MSA or Sulfuric Acid
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.
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.
