The IonPac® CS17 carboxylate-functionalized cation-exchange column is tailored for gradient separation of polyvalent and moderately hydrophobic amines, including biogenic amines and diamines, using simple aqueous eluents and elevated temperature (40 °C). The CS17 is an excellent column for use with Reagent-Free™ IC systems using Eluent Generation, which requires only a deionized water source to produce methanesulfonic acid eluent. The CS17 column is now available in capillary format (0.4 × 250 mm) offering reduced eluent consumption and reduced operating costs.

• For polyvalent and moderately hydrophobic amines, including diamines and biogenic amines
• Optimized for simple acidic gradient applications with minimal baseline shift
• Ideal alternative for amine applications using the IonPac CS14 column
• Provide improved peak shape without adding organic solvent to the eluents
• Compatible with organic solvents

The IonPac CS17 column is recommended for separation of  polar amines including alkanolamines and methylamines. It can also be used for separation of moderately hydrophobic amines, including biogenic amines, alkyldiamines, and polyamines. 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 CS17 column is also used extensively in the food industry.
