Dionex IonPac AS9-HC 阴离子交换柱 051786

使用 Thermo Scientific? Dionex? IonPac? AS9-HC 中等容量碳酸盐淋洗液阴离子交换柱分析饮用水中的痕量溴酸盐。 Dionex IonPac AS9-HC 柱专为分析饮用水中的痕量溴酸盐设计,是美国 EPA 方法 300.1 和 317.0 的色谱柱。 然而,先进的高容量 Dionex IonPac AS23 碳酸盐淋洗液阴离子交换柱则推荐用于测定臭氧处理饮用水中卤氧化物和无机阴离子,如痕量溴酸盐。

 

 

描述

环境基质中的无机阴离子和卤氧化物分析

  • 按照美国 EPA 方法 300.1 和 317.0 进行饮用水中常见阴离子和卤氧化物的合规监测

  • 轻松对臭氧处理饮用水基质中的痕量溴酸盐 (5μg/L) 进行等度分离

  • 在高难度应用中,如复杂样品基质中的痕量亚硝酸盐分析,获得出色的分析结果。

  • 与 Dionex IonPac AS9-SC 柱选择性相似,但是容量更大,对饮用水中痕量溴酸盐的分离效果更佳

  • 溶剂兼容性让您在分析含有疏水成分的样品后方便地进行柱清洗

提供多种规格,实现应用灵活性

  • 4x250mm、2x250mm、0.4x250mm 分析柱

  • 4x50mm、2x50mm、0.4x50mm 保护柱

  • 更长的 250 mm 柱,实现更复杂样品基质的更高分辨率分离

  • 更小柱内径,提高质量灵敏度,节省洗脱液和试剂,并且降低运行成本

High-Capacity Column for the Analysis of Inorganic Anions and Oxyhalides Including Bromate

Specifically designed for trace bromate in drinking water, the Thermo Scientific? Dionex? IonPac? AS9-HC column is the specified column for U.S EPA Methods 300.1 and 317.0.

  • For the analysis of oxyhalides and inorganic anions in complex sample matrices

  • Simple, isocratic method for trace bromate (5 μg/L) in ozonated drinking water matrices

  • Ideal for difficult applications, such as trace nitrite in complex sample matrices

  • Improved separation of bromate/chloride, chloride/nitrite, chlorate/nitrate analyte pairs

The Dionex IonPac AS9-HC column is a high-capacity carbonate eluent anion-exchange column with selectivity similar to the Dionex IonPac AS9-SC column. The Dionex IonPac AS9-HC column also supports the analysis of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate. The Dionex IonPac AS9-HC column is specified in validated methods such as U.S. EPA Method 300.1 and 317.0 and meets or exceeds the performance requirements of these methods.

This column separates trace bromate in drinking water matrices using an isocratic carbonate eluent and a large-loop injection. The Dionex IonPac AS9-HC column also offers good retention of fluoride out of the water dip. The column’s high capacity (190 μeq for 4 × 250 mm column) increases retention time to approximately 22 min. Use the Thermo Scientific Dionex Anion Electrolytically Regenerating Suppressor (AERS 500) with the Dionex IonPac AS9-HC column.

The Dionex IonPac AS9-HC column is offered in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary (0.4 × 250 mm). The capillary format 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 with helps reduce the operating costs.

Note: The Thermo Scientific Dionex IonPac AS23 column is the newest carbonate eluent column recommended for the analysis of oxyhalides including bromate.
