Fast Analysis of Common Inorganic Anions
Designed
specifically for compliance monitoring of inorganic anions in accordance
with U.S. EPA Method 300.0 (A) and 300.1, the Thermo Scientific? Dionex? IonPac? AS22 column represents the culmination of more than 20 years of column
development, and is a key complement to our award-winning Reagent-Free? IC (RFIC?) system. And now the Dionex IonPac AS22 column is available
in capillary format. The Dionex IonPac AS22 Capillary column is packed
with the same material as the equivalent standard bore version
(providing the same performance as a 4 mm column), but requires only
1/100th the eluent flow rate. The capillary format provides the
advantage of significantly reduced eluent consumption, which helps
reduce operating costs.
-
Fast isocratic separation of the common inorganic anions in 8 minutes
-
Isocratic separation of inorganic anions in complex sample matrices in 12 minutes
-
Carbonate peak well-resolved from the common inorganic anions
-
Meets performance requirements specified in U.S. EPA Method 300.0 (A)
-
Ideal alternative for Dionex IonPac AS4A-SC, AS12A, AS14, and AS14A inorganic anion applications
-
Simple, accurate eluent preparation with the Dionex IonPac AS22 Eluent Concentrate
-
Optimized for a 30 °C operating temperature to ensure reproducible retention times
The
Dionex IonPac AS22 column is designed for the determination of
inorganic anions and low molecular weight organic acids including
fluoride, acetate, formate, chloride, nitrite, bromide, nitrate,
phosphate, and sulfate. The Dionex IonPac AS22 column can be used with
isocratic carbonate/bicarbonate eluents and suppressed conductivity
detection. Common inorganic anions can easily be separated in a variety
of sample matrices including drinking water, wastewater, process
streams, and scrubber solutions.
The Dionex IonPac AS22 column
can be used in combination with the Eluent Generator and the
Electrolytic pH Modifier (EPM) which automatically produce potassium
carbonate/bicarbonate eluents from water. The Dionex IonPac AS22 column
is the newest carbonate eluent column recommended for fast analysis of
inorganic anions and is an ideal alternative, using
carbonate-bicarbonate eluents, for Dionex IonPac AS4A-SC, AS12A, AS14,
and AS14A inorganic anion applications.
Note: Use the Thermo
Scientific Dionex ASRS 300 Anion Self-Regenerating Suppressor with the
Dionex IonPac AS22 column for eluent suppression.
