Determination of inorganic anions using Thermo Scientific™ Dionex™ IonPac™ AS18-4µm column with a high-pressure ion chromatography system.

Thermo Fisher Scientific has announced a new technical note about the determination of inorganic anions in water samples using our 4 µm ion-exchange column (Thermo Scientific™ Dionex™ IonPac™ AS18-4µm column).

Technical Note 127: Efficient and Fast Separations of Inorganic Anions in Water Samples Using a 4 µm Particle Size Microbore Column with a High-Pressure Ion Chromatography System presents the advantages of using the small-particle size microbore (2 mm i.d.) Dionex IonPac AS18-4µm column, in combination with the high-pressure capillary Ion Chromatography system, Thermo Scientific™ Dionex™ ICS-5000+HPIC™ system to obtain fast and efficient separation of inorganic anions in municipal drinking and wastewater samples.

In 1993, the U.S. EPA Method 300.0 (A) defined the use of the Thermo Scientific™ Dionex™ IonPac™ AS4A anion-exchange column to determine inorganic anions in environmental waters using a manually prepared carbonate/bicarbonate eluent and suppressed conductivity detection.

With the introduction of Reagent-Free™ ion chromatography (RFIC™) systems, hydroxide-based eluents were electrolytically generated inline on anion-exchange columns optimized for hydroxide chemistry.

The Dionex IonPac AS18 column was developed as an alternative to the AS4A column; the AS18 is designed for use with EPA Method 300.0 (A) using Electrolytically Generated hydroxide eluents. These smaller resin particles allow an optimal combination of fast speed and high resolution.
