• Separation of common anions and low molecular weight organic acids
• For high-purity water matrices and chemical and petroleum samples Suitable for complex matrices including
• Compatible with organic solvents to enhance analyte solubility, change column selectivity, and facilitate effective column cleaning

• Improved efficiency and resolution compared to Dionex IonPac AS15 columns
• Transfer applications from Dionex IonPac AS15 columns due to similar selectivity Easily transferred to AS28-Fast-4µm columns

By using smaller resin particles, higher High resolution and generates column backpressure in excess of 3000 psi at standard flow rates. Using 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 Thermo Scientific Dionex ICS-4000 Capillary HPIC System.

Dionex IonPac AS28-Fast-4µm capillary columns are the same as standard bore and microbore because they use the same packing material Dionex IonPac AS28-Fast-4µm columns perform identically. 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.

• 4 x 150mm and 2 x 150mm columns
• 4 x 30mm and 2 x 30mm guarded Housing
• 0.4 x 150mm capillary column
• 0.4 x 35mm capillary guard column
• Smaller column inner diameter, improved sensitivity, saving eluents and reagents, and Reduce running costs
