的詳細介紹
Thermo Scientific Dionex IonPac AS26 Hydroxide-Selective Anion-Exchange Column
For Separation of Haloacetic Acids and Bromate in Drinking Water Using Two-Dimensional Ion Chromatography (2D-IC) Analysis
The Thermo Scientific Dionex IonPac* AS26 hydroxide-selective anion-exchange column is specifically designed
for 2D-IC separation of haloacetic acids (HAAs) in drinking water. The
capacity and selectivity of this column enables analysis of haloacetic
acids in drinking water at low-μg/L concentrations. The Dionex IonPac
AS26 column is available in standard bore (4 × 250 mm), microbore (2 ×
250 mm), and capillary (0.4 × 250 mm) formats, supporting flow rates
from 10 μL/min to 3 mL/min.
-
High capacity: 250 μeq per column (4 × 250 mm)
-
Determines HAAs in high-ionic-strength matrices without sample pretreatment
-
Column selectivity optimized for a 15 oC operating temperature
-
Compatible with HPLC organic solvents
-
Used as second-dimension column in 2D-IC method for HAAs (0.4 × 250 mm)
