The new IonPac CS18 cation-exchange column is tailored for the separation of polar amines including alkanolamines and methylamines, and moderately hydrophobic amines including biogenic amines, alkyl diamines, and polyamines using simple aqueous eluents and elevated temperature. The CS18 is ideally used with RFIC^TM  systems for automatic methanesulfonic acid eluent generation. 

• Universal column for amines including alkanolamines and methylamines in diverse sample matrices.
• Universal column for moderately hydrophobic amines including biogenic amines, alkyl diamines, and polyamines.
• Optimized for simple isocratic or gradient separations with minimal baseline shift during gradients.
  Simplified Reagent-Free Ion Chromatography (RFIC) operation provided by the Eluent Generator. Requires only a deionized water source to produce methanesulfonic acid (MSA) eluent. 
• Eluent suppression using the CSRS^® ULTRA II or CAES^® technology provides Reagent-Free electrolytic suppression with minimal baseline shift during gradients and enhanced analyte sensitivity.
• Compatible with moderate amounts of organic solvents, excluding alcohols, to enhance analyte solubility for effective elution of hydrophobic amines, to modify column selectivity, or for effective column clean-up.
• Moderate capacity: 290 µeq/col. (2 x 250 mm column).   Only a modest acid concentration is required to elute amines.
• Sample matrices include power plant waters treated with ammonium, morpholine or ethanolamine, chemical additives, chemical process solutions, scrubber solutions,  personal care products, and food samples.
  

The IonPac CS18 cation-exchange column is of  moderate capacity and hydrophobicity targeted for isocratic and gradient separations of polar amines including alkanolamines and methylamines and moderately hydrophobic amines including biogenic amines, alkyl diamines, and polyamines. The CS18 is ideally used with RFIC systems for automatic methanesulfonic acid eluent generation. 

The CS18 is recommended for polar amines and moderately hydrophobic amines using suppressed conductivity detection. Optimized isocratic and gradient methanesulfonic acid eluents with suppressed conductivity detection are recommended to separate a variety of amines and the common inorganic cations. The CS18 column with nonsuppressed conductivity detection is recommended when extended calibration linearity for ammonium or weak bases is required. The CS18 can be used for many of the nonsuppressed applications supported by the IonPac SCS-1 column but with much greater column stability. The IonPac CS18 is targeted for power generation, chemical, petrochemical, food samples, and personal care products applications. 

Use the Cation Self-Regenerating Suppressor (CSRS ULTRA) or the Cation Atlas^® Electrolytic Suppressor, CAES^®, (up to 25 µeq/column) with the CS18 column.
