Thermo Scientific Dionex IonPac CS16-4μm and CS16-Fast-4μm IC Columns

Analyze disparate concentration ratios up to 10,000:1 of close-eluting cations such as ammonium and sodium using Thermo Scientific™ Dionex™ IonPac™ CS16-4μm and CS16-Fast-4μm columns. Designed specifically for the analysis of cations at diverse concentration ratios, this high-capacity column combines the selectivity of the Dionex IonPac CS16 column with fast, high resolution separations. Compared to the Dionex IonPac CS16 column, the new Dionex IonPac CS16-4μm and CS16-Fast-4μm columns use smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration, and more reliable results.

Highest Resolution Separation of Ammonium and Sodium at Disparate Concentration Ratios up to 10,000:1 in Diverse Matrices

• 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

Use with a High-Pressure IC System

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.

Reduce Operating Costs With Lower Eluent Requirements

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.

Multiple Formats Available for Application Flexibility

• 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
