IonPac CS16 Cation-Exchange Column

High-Capacity Carboxylate-Functionalized Column for Disparate Sodium and Ammonium Concentrations

The IonPac? CS16 is the column of choice for disparate concentration ratios of adjacent eluting cations such as sodium and ammonium in diverse sample matrices. The high-capacity, high-resolution CS16 column can be used for short-chained amines, including alkylamines and alkanolamines, in diverse sample matrices. The CS16 column is now available in capillary format (0.5 × 250 mm) offering reduced eluent consumption and reduced operating costs.

  • For disparate concentration ratios of close-eluting cations such as ammonium and sodium in complex matrices
  • Ideal for trace-level ammonium in high concentrations of sodium
  • Ideal for trace-level sodium in high concentrations of ammonium or amines
  • Best carboxylate-functionalized column to tolerate samples with low pH
  • Isocratic acid eluent and elevated temperature (40 °C) required for sodium: ammonium ratios to 1:10,000
  • Gradient MSA eluent and elevated temperature required for sodium: ammonium ratios up to 1:20,000
  • Useful for short-chained amines, including alkylamines and alkanolamines
  • Compatible with organic solvents excluding alcohols

Using an isocratic acid eluent and elevated temperature (40 °C) coupled with suppressed conductivity, ratios up to 10,000:1 of sodium and ammonium can be resolved in less than 20 min. Sample matrices include environmental waters; power plant waters treated with ammonium, morpholine or ethanolamine; chemical additives; chemical process solutions; scrubber solutions; plating baths; and industrial solvents. The CS16 is designed for use in most IonPac CS15 applications.

The CS16 column has the highest capacity among Dionex carboxylate-based cation columns, resulting in improved loadability and resolution. Use the CS16 with the Eluent Generator for simplified, consistent methanesulfonic acid eluent preparation. Use the Cation Self-Regenerating Suppressor (CSRS? 300) with standard or microbore CS16 columns or the Cation Capillary Electrolytic Suppressor (CCES? 300) with the CS16 capillary column.
