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-6000 HPIC system is required. Use the format that fits your lab
• 4 x 150 mm, 2 x 150 mm analytical columns
• 4 x 30 mm, 2 x 30 mm guard columns
• Shorter 150 mm columns facilitate faster runs while the smaller particle size maintains a higher resolution separation 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).
