IonPacAS20阴离子交换色谱柱,弱阴离子交换柱WAX/DEAE

IonPac AS20 阴离子交换色谱柱
The IonPac AS20 是一款高容量，氢氧根体系阴离子交换色谱柱，用来检测饮用水、地表水及其它各种样品中痕量的高氯酸盐。该柱符合U.S. EPA 314.1 标准(确定的方法)。
For determination of trace perchlorate using suppressed conductivity detection

The AS20 hydroxide-selective anion-exchange column is specifically designed for the determination of trace concentrations of perchlorate in drinking water, surface water, and groundwater matrices. The capacity and selectivity of the AS20 ensures that
perchlorate can be quantified at low μg/L concentrations using suppressed conductivity detection even in the presence of very high concentrations of chloride, carbonate, and sulfate.
• Recommended for US EPA Method 314.1 (Confirmatory Method)
• High capacity: 310 μeq per column. (4 × 250 mm)
• Use the Cryptand C1 Concentrator Column for sample preconcentration
• Simplified Reagent-Free IC operation provided by the Eluent Generator
• ASRS 300 provides RFIC operation with low background and enhanced analyte sensitivity
• Column selectivity is optimized for 30 °C operating temperature
• Compatible with organic solvents
The AS20 is the specified column in US EPA Method 314.1 (Confirmatory Method). The Cryptand C1 Concentrator Column is the specified concentrator column for sample preconcentration in that method.
The AS20 column is ideally used with an RFIC system for best detection limits. Use the Anion Self-Regenerating Suppressor (ASRS 300) with the AS20 column for eluent suppression.
