The IonPac^® CS11 is designed for the isocratic separation of inorganic cations using hydrochloric acid or diaminopropionic acid eluents. The CS11 can also be used for ethanolamines if divalent cations are not present. The CS12A column is the recommended column for fast analysis of inorganic cations. The CS17 column is the recommended hydrophobic amines including biogenic amines and diamines. The CS18 column is recommended for polar amines inlcuding alkanolamines and methylamines. The CS18 is also recommended for moderately hydrophobic amines including biogenic amines and alkyldiamines..

The CS11 can be used for analysis of the common inorganic cations.
The CS11 column can be used for ethanolamines if divalent cations are not of interest.
The CS12A column provides improved performance for fast analysis of inorganic cations and ammonium.
The CS17 column is recommended for hydrophobic and polyvalent amines.
The CS18 column is recommended for polar amines including alkanolamines and methylamines.
The CS18 is also recommended for moderately hydrophobic amines inlcuding biogenic amines and alkyldiamines.
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 IonPac CS11 is a moderate-capacity, sulfonic acid functionalized, cation-exchange column designed for the isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using hydrochloric acid or diaminopropionic acid eluents with suppressed conductivity detection. The common inorganic cations can be determined in diverse sample matrices including drinking water, power plant waters, soil extracts, acid digests, chemical additives, chemical process solutions, scrubber solutions, and plating baths. The CS11 has similar selectivity to the CS10 column, but with 1.75-fold increase in capacity. Use the Cation Self-Regenerating Suppressor (CSRS^® ULTRA) with the CS11 column.

CS12A Column

The IonPac^® CS12A is the recommended column for the fast separation of mono- and divalent cations.

CS17 Column

The IonPac^® CS17 is recommended column for hydrophobic and polyvalent amines, including biogenic amines amd diamines.

CS18 Column

The new 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.

SRS 300

The Self-Regenerating Suppressor, (SRS^® 300), is used for electrolytically regenerated suppression of ion chromatography applications requiring high capacity, fast start-up, and sensitivity.
