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).
