Description

Length (Metric): 50 mm
Diameter (Metric): 4 mm
Column Type: Guard Column
Unit Size: Each 1
High Capacity for Higher Resolution
• Requires longer retention times, but with higher resolution
• Facilitates rapid analysis of organic acids and anions in well-characterized samples
• Ideal for organic acids and anions in complex sample matrices or uncharacterized samples
• Recommended for monovalent and divalent organic acids Reduce Operating Costs With Lower Eluent Requirements The new Dionex IonPac AS11-HC Capillary column is packed with the same material as the equivalent standard bore and microbore versions (providing the same performance as a 4 mm and 2 mm column) using only 1% of the eluent flow rate, which helps reduce operating costs. Use the Thermo Scientific™ Dionex™ IonPac™ ICE-AS1 or ICE-AS6 columns for organic acids in high-ionic-strength samples.

Application Note

Dionex™ IonPac™ AS11-HC 4 mm guard column is used as the guard component for IonPac AS11-HC anion-exchange ion chromatography methods that separate inorganic anions and organic acid anions in complex sample matrices. This configuration is 4 mm in diameter and 50 mm long and is intended for use with the matching IonPac AS11-HC analytical column. The AS11-HC chemistry is designed for high-capacity separations using hydroxide-gradient conditions and is suitable for complex matrices such as chemical wastewater effluents and fermentation broth solutions. The column family supports analysis of monovalent and divalent organic acids, including carboxylates such as quinate, lactate, acetate, propionate, formate, and butyrate. The guard column is rated to 4000 psi (275 bar) and supports solvent conditions from pH 0 to 14 with 0–100% HPLC solvents. Its role in the matched column set is to provide a short front-end ion-exchange bed before the main analytical column while maintaining compatibility with the same separation chemistry. This makes it appropriate for demanding IC workflows where complex samples are analyzed with the AS11-HC method platform.
