The IonPac^®  CS18 is a moderate-capacity cation-exchange column recommended for the separation of polar amines including alkanolamines and methylamines and moderately hydrophobic amines including biogenic amines, diamines, and polyvalent amines using simple aqueous eluents and elevated temperature.

The IonPac^®  CS17 is a moderate-capacity, cation-exchange column designed for gradient profiling and the determination of hydrophobic amines, including biogenic amines and diamines using simple aqueous eluents and elevated temperature.

The IonPac CS16 is a high-capacity, cation-exchange column and is the recommended column for the determination of disparate concentration ratios of sodium and ammonium in diverse sample matrices, including environmental waters, power plant waters, chemical additives, scrubber solutions, and plating baths.

The IonPac^® CS15 is a high-capacity, cation-exchange column designed for the determination of very disparate concentration ratios of sodium and ammonium in diverse sample matrices. Elevated temperature is required, along with an isocratic acid or solvent eluent. The CS15 can also be used for alkanolamines and trace ethanolamine in high-ammonium or high-potassium concentrations.

The IonPac^® CS14 is a moderate-capacity, cation-exchange column that can be used for the determination of aliphatic amines, aromatic amines, polyamines, and quaternary ammonium ions in diverse sample matrices.

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

The IonPac CS12 is a high-capacity, cation-exchange column designed for the fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices.

The IonPac CS11 is a moderate-capacity, sulfonate-functionalized, cation-exchange column designed for the isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using hydrochloric acid or diaminopropionic acid eluents. The CS11 can also be used for ethanolamines if divalent cations are not present.

The IonPac CS10 is a moderate-capacity, sulfonate-functionalized, cation-exchange column designed for the isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using hydrochloric acid or diaminopropionic acid eluents. The CS10 can also be used for biogenic amines.
