Compared to the Thermo Scientific™ Dionex™ IonPac™ AS23 columns, these columns use smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results. Designed Specifically for Trace Bromate Analysis in Drinking Water
• Use the Dionex IonPac AS23-4μm for diverse matrices including drinking water, ground water, and waste water.
• High capacity allows routine drinking water analysis without sample pretreatment or preconcentration.
• Improved efficiencies and resolution compared to the Dionex IonPac AS23 column.
• Easily transfer applications from the Dionex IonPac AS23 column to the AS23-4μm column due to the similar selectivity.
• Compatible with organic solvents to enhance analyte solubility, modify column selectivity, and facilitate effective column clean-up. Use With a High-Pressure IC System Higher resolution is achieved through the use of smaller resin particles, which produce a column backpressure over 3000psi at the standard flow rates. A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-5000^+ HPIC™ or the Thermo Scientific™ Dionex™ Integrion™ HPIC™ system is required to operate this column under standard conditions and take advantage of elevated flow rates and faster run times. Multiple Formats Available
• 4 x 250 mm and 2 x 250 mm analytical columns
• 4 x 50 mm and 2 x 50 mm guard columns Note: Use the Dionex AS23 Eluent Concentrate for simple, accurate eluent preparation.
