Industrial Chromatography
Separate polar amines with the Thermo Scientific™ Dionex™ IonPac™ CS18 Cation-Exchange Column. This low-capacity, carboxylate-functionalized column is specifically optimized for the separation of common cations, small polar amines, and moderately hydrophobic and polyvalent anions using simple aqueous eluents and elevated temperatures. However, the newer Thermo Scientific™ Dionex™ IonPac™ CS19 or Dionex IonPac CS19-4µm Cation Exchange Columns are the recommended columns for these applications.

Description

Cation and Amine Separations Using Suppressed and Non-suppressed Conductivity Detection
  • Low-capacity column optimized for the isocratic and gradient separations of polar amines, moderately hydrophobic amines, and polyvalent cations
  • Can be used with suppressed and nonsuppressed conductivity detection
  • Nonsuppressed conductivity detection is recommended to extend calibration linearity for ammonium or weak bases
  • Can also be used for many of the nonsuppressed applications supported by the Dionex IonPac SCS-1 column but with much greater column stability
  • Optimized for simple acidic gradient separations with minimal baseline shift
  • Low capacity facilitates modest acid concentrations to elute polyvalent cations
  • Compatible with moderate amounts of organic solvents, excluding alcohols, to enhance analyte solubility, modify column selectivity, and facilitate effective column clean-up
Formats Available for Application Flexibility
  • 2x250mm analytical columns
  • 2x50mm guard columns
  • Longer 250mm columns facilitate higher resolution separations of more complex sample matrices
  • Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
