Industrial Chromatography

Attain the optimal combination of chromatographic speed and resolution using the Thermo Scientific™ Dionex™ IonPac™ AS22-Fast-4µm column. Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Method 300.0 (A), this moderate capacity column combines the selectivity of the Dionex IonPac AS22-Fast column with fast high resolution separations. Compared to the Dionex IonPac AS22-Fast column, the new Dionex IonPac AS22-Fast-4µm column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results.

Fast separation of common inorganic anions with excellent resolution
  • Obtain the highest peak efficiency, through the use of smaller resin particles, of common inorganic anions in diverse sample matrices
  • Attain fast isocratic separation of the common inorganic anions in less than 5 min
  • Perform compliance monitoring of common anions in drinking water as specified in U.S. EPA Method 300.0 (A)
  • Achieve excellent separation of inorganic anions and low-molecular weight acids in diverse sample matrices
  • Obtain high peak efficiency and increased peak resolution for more consistent integration and more reliable results
  • Transfer application easily--this 4µm column has the the same selectivity as the Dionex IonPac AS22-Fast column
  • Achieve excellent resolution of the carbonate peak away from the common inorganic anions
  • Reduce run time without loss of resolution compared to the Dionex IonPac AS22-Fast column
  • Faster alternative, using carbonate/bicarbonate eluents, for Dionex IonPac AS4A-SC, AS12A, AS14, AS14A and AS22 inorganic anion applications
  • Compatible with organic solvents to enhance analyte solubility, modify column selectivity, or allow effective column cleanup

Use with a high-pressure IC system

Higher resolution is achieved through the use of smaller resin particles, which can produce a column backpressure over 3000 psi. When operating the Dionex IonPac AS22-Fast-4µm column, a high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC or the Dionex ICS-4000 HPIC is required.

Reduce operating costs with lower eluent requirements

The Dionex IonPac AS22-Fast-4µm capillary column provides the same performance as the standard bore and microbore Dionex IonPac AS22-Fast-4µm columns because it is packed with the same material. Operating costs are reduced because the capillary system operates at only 1% of the eluent flow rate of the standard bore system, requiring less eluent and producing less waste.

Use the cormat that fits your lab
  • 4x150mm, 2x150mm analytical columns
  • 4x30mm, 2x30mm guard columns
  • 0.4x150mm capillary column, 0.4x35mm capillary guard column
  • Shorter 150mm columns facilitate faster runs while the smaller particle size maintains a higher resolution separation
  • Capillary columns provide reduced operating and waste disposal costs through eluent conservation

Note: For simple, accurate eluent preparation, use the Dionex IonPac AS22 Eluent Concentrate or the Dionex Eluent Generator (Dionex EGC 500 K2CO3 cartridge with Dionex EPM 500 pH modifier).
