The Thermo Scientific 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
