Dionex IonPac AS23  阴离子交换柱 064149

利用 Thermo Scientific? Dionex? IonPac? AS23 碳酸盐淋洗液阴离子交换柱测定饮用水、地下水、废水和其他多种样品基质中的痕量溴酸盐和其他卤氧化物。 该款色谱柱专为测定饮用水基质中的痕量溴酸盐(一种臭氧消毒的毒性副产物)设计,推荐用于此用途。 该款色谱柱的高容量和选择性有助于在存在高浓度氯化物、硫酸盐和碳酸盐的情况下测定饮用水中低 μg/L 水平的溴酸盐。 Dionex IonPac AS23 柱符合美国 EPA 方法 300.0 和 300.1 的性能要求。

 

 

描述

饮用水中的痕量溴酸盐分析
按照美国 EPA 方法 300.0 和 300.1 进行饮用水中常见阴离子和卤氧化物的合规监测
使用等度碳酸盐/碳酸氢盐淋洗液以及抑制型电导检测,轻松对饮用水基质中的痕量溴酸盐进行分析
选择性得到优化,确保在存在超高浓度氯化物、硫酸盐和碳酸盐的情况下对溴酸盐实现低 ppb 水平的测定
对饮用水、地下水、废水和其他各种样品基质中的卤氧化物和常见无机阴离子进行分离
高容量,无需进行样品预处理或预浓缩即可分析大多数饮用水
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
更低的淋洗液要求,降低运行成本
由于使用相同的填料,Dionex IonPac AS23 毛细管柱提供的性能与标准孔和微孔 Dionex IonPac AS23 柱相同。 由于毛细管系统运行的淋洗液流速仅为标准孔系统的 1%,需要的淋洗液更少,产生的废液也更少,从而降低了运行成本。

提供多种规格,实现应用灵活性
4x250 mm、2x250 mm 分析柱
4x50 mm、2x50 mm 保护柱
0.4x250mm 毛细管柱、0.4x50mm 毛细管保护柱
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
注: 要实现简单准确的淋洗液制备,请使用 Dionex IonPac AS23 浓缩淋洗液。

Precise, Isocratic Analysis of Trace Oxyhalides and the Common Inorganic Anions

The Thermo Scientific? Dionex? IonPac? AS23 carbonate eluent anion-exchange column is specifically designed for trace bromate in drinking water. Its high-capacity and selectivity enables determination of bromate in drinking water at the low μg/L level. The Dionex IonPac AS23 column meets the performance requirements of U.S EPA Methods 300.0 and 300.1. The Dionex IonPac AS23 column is offered in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm) and capillary (0.4 × 250 mm). The capillary formats 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.

  • Optimized for isocratic carbonate/bicarbonate eluent

  • Recommended column for trace bromate in drinking water matrices

  • Meets performance requirements specified in U.S. EPA Methods 300.0 and 300.1

  • Ideal alternative for the Thermo Scientific Dionex IonPac AS9-HC oxyhalide and inorganic anion applications

  • Simple, accurate eluent preparation with the Dionex IonPac AS23 Eluent Concentrate

  • Optimized for a 30 °C operating temperature to ensure reproducible retention times

  • Compatible with organic solvents to enhance analyte solubility 

The Dionex IonPac AS23 column is designed for the analysis of oxyhalides and the common inorganic anions including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, ground water, wastewater, and other diverse sample matrices.

The Dionex IonPac AS23 column is the newest carbonate eluent column recommended for the analysis of oxyhalides including bromate. It can be used in combination with the Eluent Generator and the Electrolytic pH Modifier (EPM) which automatically produces potassium carbonate/bicarbonate eluents from water. The Dionex IonPac AS23 column is an ideal alternative, using carbonate-bicarbonate eluents, for Dionex IonPac AS9-HC applications.
