• 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-5000+ HPIC™ or the Thermo Scientific Dionex ICS-4000 Capillary 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 and IonPac CS16-Fast-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.

• 4 x 250 mm, 4 x 150 mm, 2 x 250 mm, and 2 x 150 mm analytical columns
• 4 x 50 mm, 4 x 30 mm, 2 x 50 mm, and 2 x 30 mm analytical guard columns
• 0.4 x 250 mm and 0.4 x 150 mm capillary columns
• 0.4 x 50 mm and 0.4 x 35 mm capillary guard columns
• 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
