Dionex IonPac AS24 阴离子交换柱 064153

Dionex IonPac AS24 阴离子交换色谱柱

使用 Thermo Scientific? Dionex? IonPac? AS24 分析柱和保护柱，可分离饮用水样品中的卤乙酸和溴酸盐。 这种高容量氢氧化物选择性阴离子交换柱专为在质谱检测前端，分离饮用水中的卤乙酸和溴酸盐而研制。 2x250mm 为美国 EPA 方法 557 中指定的柱规格。 Dionex IonPac AS24 的柱容量和选择性能够确保对饮用水中的低至 μg/L (ppb)级 浓度卤乙酸进行分析。 该柱也非常适合开发特殊的应用方法，能对环境阴离子，包括复杂基质中无机阴离子、卤氧化物、含氧阴离子和有机酸等实现卓越分离。

描述

色谱分析性能优异

• 美国 EPA 方法 557 指定 (2x250mm)

• 高柱容量（140μeq/柱，2x250mm）使得进样复杂基质时不会出现色谱柱过载，同时又能始终对低浓度分析物获得极好的峰形

• 当测定高离子强度基质中的卤乙酸时，不需进行样品预处理

• 可在美国 EPA 方法 302.0 所述的关于溴酸盐的 2D 方法中用作第二维色谱柱（2x250 mm）

• 尤其适合在梯度洗脱下使用 Reagent-Free? 离子色谱（RFIC?）系统开发专门应用方法

• 可在环境温度或更高温度下运行；经过优化选择在 15oC 的操作温度下可确保卤乙酸的回收率具有良好重现性

• 与 HPLC 有机溶剂兼容，操作灵活、易于清洗

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
