Thermo Fisher 78032 Each 1 Dionex IonPac AS11-HC-4μm,ICcolumn,capillary guard column

• Monovalent and divalent organic acids
• Organic acids and inorganic anions in complex sample matrices or unknown samples

Use high-capacity columns to achieve higher resolution

• Facilitate the injection of higher concentration samples without causing column overloading or peak broadening
< /ul>

Use of smaller resin particles (4µm) improves performance

• Easily transfer applications from Dionex IonPac AS11-HC columns to 4µm column
• Selectivity similar to Dionex IonPac AS11-HC column
• Improved peak resolution and more consistent results
• Can improve monovalent carboxylic acids ( including quinate, lactate, acetate, propionate, formate, and butyrate)

Dionex IonPac AS11-HC-4µm columns are available in three sizes: 4x250 mm, 2x250 mm and 0.4x250mm. Capillary columns reduce eluent consumption, helping to reduce operating costs.

For use with high-pressure capillary ion chromatography systems

Smaller resin particles for Dionex IonPac AS11-HC-4µm columns can be produced at standard flow rates Back pressure in excess of 3000 psi. Running this column under standard conditions requires the use of a high-pressure capillary IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ or Dionex ICS-4000 Capillary HPIC system.

For best performance

• Use Thermo Scientific™ Dionex™ IonPac™ AS11 columns in well-characterized samples. Rapid analysis of organic acids and anions
• For organic acids in high ionic strength samples, use Thermo Scientific™ Dionex™ IonPac™ ICE-AS1 or ICE-AS6 columns
