的詳細(xì)介紹
IonPac AS24 Hydroxide-Selective Anion-Exchange Column
For Separation of Haloacetic Acids and Bromate in Drinking Water
The Thermo Scientific Dionex IonPac? AS24 is a high-capacity hydroxide-selective anion-exchange column
optimized for the separation of haloacetic acids (HAAs) as well as a
variety of environmental anions. The capacity and selectivity enables
analysis of haloacetic acids in drinking water at low-μg/L
concentrations. The Dionex IonPac AS24 2 × 250 mm column is specifically
designed for separation of haloacetic acids in drinking water prior to
MS or MS/MS detection and is the specified column in US EPA Method 557.
-
Specified column for US EPA Method 557 (2 × 250 mm)
-
High capacity: 140 μeq per column (2 × 250 mm)
-
Determine HAAs in high-ionic strength matrices without sample pretreatment
-
Column selectivity is optimized for a 15 oC operating temperature
-
Compatible with HPLC organic solvents
-
Used as second dimension column in 2-D method for bromate in US EPA Method 302.0 (2 × 250 mm)
-
Extended application capabilities providing excellent separation of environmental anions
