Compared to Thermo Scientific™ Dionex™ IonPac™ CS19 columns, this column uses smaller resin particles to improve separation efficiency, resulting in more accurate peak integration and more reliable results.

Achieve extremely high resolution separation of common cations and small polar amines in a variety of matrices
  • By using smaller particle size resin particles, Enables the highest resolution separation of common cations and small polar amines within complex sample matrices
  • Improved peak efficiency and increased resolution, resulting in more consistent integration and more reliable results
  • li>
  • Easily transfer applications from Dionex IonPac CS19 columns to 4 µm columns due to similar selectivity
  • Can handle small polar amines including alcoholamines and methylamines and simple gradient separations of moderately hydrophobic amines and polyvalent amines, including biogenic amines and alkyl diamines
  • High capacity facilitates injection of high-concentration samples without causing column overloading or peak broadening
  • li>
  • Compatible with appropriate amounts of organic solvents (excluding alcohols) to enhance analyte solubility, optimize column selectivity, or facilitate effective column cleaning
Compatible with high-pressure IC systems Use
By using smaller resin particles, higher resolutions can be achieved and generate column backpressures in excess of 3000 psi at standard flow rates. Running this column under standard conditions and taking advantage of high flow rates and short run times requires a high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ or Dionex ICS-4000 capillary HPIC system.

Lower eluent requirements, lower operating costs
Using the same packing material, Dionex IonPac CS19-4µm capillary columns offer the same chromatography capabilities as standard bore and microbore Dionex IonPac CS19-4µm columns. columns with the same performance. Because capillary systems operate at only 1% of the eluent flow rate of standard orifice systems, less eluent is required and less waste is produced, thus reducing operating costs.

Available in a variety of specifications for application flexibility

  • 4x250mm, 2x250mm analytical columns
  • 4x50mm, 2x50mm guard columns
  • 0.4x250 mm capillary column, 0.4x50mm capillary guard column
  • Longer 250mm column to achieve higher resolution separation of more complex sample matrices
  • More Small column inner diameter improves mass sensitivity, saves eluents and reagents, and reduces operating costs
