• Recommended for trace-level ammonium in high concentrations of sodium without sample pretreatment
• Recommended for trace-level sodium in high concentrations of ammonium without sample pretreatment
• Use the 250 mm Dionex IonPac CS16-4μm for complex matrices
• Use the 150 mm Dionex IonPac CS16-Fast-4μm for faster analyses in simple matrices.
• Easily transfer applications from the Dionex IonPac CS16 column to the 4 μm columns due to the similar selectivity
• High capacity facilitates injection of more concentrated samples without column overloading or peak broadening
• Compatible with organic solvents, excluding alcohols, to enhance analyte solubility, modify column selectivity, and facilitate effective column clean-up

Higher resolution is achieved through the use of smaller resin particles, which produce a column backpressure over 3000 psi at the standard flow rates. A high-pressure IC system, such as the Thermo Scientific™ Dionex™ ICS-6000+ HPIC™ system, is required to operate this column under standard conditions and take advantage of elevated flow rates and faster run times.

The Dionex IonPac CS16-4μm capillary columns provide the same performance as the standard bore and microbore Dionex IonPac CS16-4μm columns because they are 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.

• Dionex IonPac CS16-4μm: Available in 4 mm, 2 mm, and 0.4 mm formats
• Dionex IonPac CS16-Fast-4μm: Available in 4 mm and 2 mm formats
• Longer 250 mm columns facilitate higher resolution separations of more complex sample matrices
• Shorter 150 mm columns provide faster analyses of simple matrices
• Smaller i.d. columns provide higher mass sensitivity, eluent and reagent conservation and lower operating costs
