Complex sample matrices such as chemical wastewater effluents and fermentation broth solutions containing a variety of inorganic anions and organic acids can be analyzed using the high resolution Dionex IonPac AS11-HC-4μm column. Appropriate analytes include:
• Monovalent and divalent organic acids
• Organic acids and inorganic anions in complex sample matrices or uncharacterized samplesAchieve Higher Resolution With High Capacity Columns
• Facilitates injection of more concentrated samples without column overloading or peak broadeningEnjoy Higher Performance With the Smaller 4μm Resin Particle Size
• Easily transfer applications from the Dionex IonPac AS11-HC column to the 4μm column
• Get similar selectivity as the Dionex IonPac AS11-HC column
• Increased peak resolution for more consistent results
• Obtain improved separation for monovalent carboxylic acids, including quinate, lactate, acetate, propionate, formate, and butyrateUse the Format That Fits Your Lab The Dionex IonPac AS11-HC-4μm column is available in three formats: 4x250 mm, 2x250 mm, and 0.4x250mm. The capillary format provides reduced eluent consumption, which helps reduce operating costs.Use With a High-Pressure Capillary IC System The smaller resin particles used in the Dionex IonPac AS11-HC-4μm column produces a backpressure over 3000 psi at the standard flow rates. A high-pressure capillary IC system, such as the Thermo Scientific™ Dionex™ ICS-5000+ HPIC™ or the Dionex ICS-4000 Capillary HPIC system is required to operate this column under standard conditions.For Best Performance
• Use the Thermo Scientific™ Dionex™ IonPac™ AS11 column for fast analysis of organic acids and anions in well-characterized samples
• Use the Thermo Scientific™ Dionex™ IonPac™ ICE-AS1 or ICE-AS6 columns for organic acids in high-ionic-strength samples
