的詳細介紹
IonPac AS15 Hydroxide-Selective Anion-Exchange Column
For Trace-Level Concentrations of Inorganic Anions and Low-Molecular Weight Organic Acids
The IonPac? AS15 column was designed specifically for analysis of trace anions in
high-purity water matrices, for the semiconductor and power generation
industries. Its high capacity and selectivity enable the determination
of trace-level concentrations of inorganic anions and
low-molecular-weight organic acids in high-purity water matrices. The
new IonPac AS15 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.
-
AS15-5μm (3 × 150 mm) column for high efficiency, fast analysis (15 min)
-
AS15-9μm (2 × 250, 4 × 250 mm, and 0.4 × 250 mm) columns for higher-capacity applications
-
Column selectivity optimized for 30 °C operating temperature
-
Superior resolution of early-eluting anions (fluoride, glycolate, acetate, and formate)
This
column is ideal for use with large-loop injections. Use the AC15
concentration column for ultratrace (ppt) analyses. Use with eluent
generation for simplified eluent preparation. Use the Anion
Self-Regenerating Suppressor? (ASRS? 300) or the Anion Capillary Electrolytic Suppressor (ACES? 300) with the AS15 column for eluent suppression.
