产品介绍

Dionex  IonPac AS26 阴离子交换柱



利用 Thermo Scientific? Dionex IonPac AS26 柱，以高灵敏度分离饮用水样品中的卤乙酸和溴酸盐。 在二维 IC (2D-IC) 方法的二维分离中使用该款高容量氢氧化物选择性阴离子交换柱时，可检测低 μg/L (ppb) 水平的卤乙酸。



描述

针对卤乙酸的 2D-IC 测定进行了优化

Dionex IonPac AS26 毛细管柱专为在使用如 Thermo Scientific? Dionex? IonPac? AS24A 4x250mm 柱等色谱柱进行一维分离后对饮用水中的卤乙酸进行二维分离而设计。 该款色谱柱也可用于测定痕量溴酸盐，同时适用于使用梯度洗脱的 Reagent-Free 离子色谱 (RFIC?) 系统的特殊应用开发。

降低运行成本

  • 毛细管和微孔需要的淋洗液更少，从而降低了运行成本

  • 优异的色谱分析性能

  • 针对氢氧化物流动相进行优化

  • 高容量： 250μeq 每柱 (4x250mm)

  • 在 2D-IC 中无需样品预处理即可测定高离子强度基质中的卤乙酸

  • 可在室温或高温环境下操作；选择性在 15oC 操作温度下达到最佳

  • 兼容 HPLC 有机溶剂

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)
