使用 Thermo Scientific? Dionex? IonPac? AS14A 碳酸盐淋洗液阴离子交换柱,可实现对饮用水、废水、食品和饮料、洗涤液等多种复杂基质中无机阴离子的快速等度分离。 Dionex IonPac AS14A 柱满足或超出了美国 EPA 方法 300.0 (A) 的要求。 但是,对于无机阴离子的快速分析,建议使用*进的 Dionex IonPac AS22 碳酸盐淋洗液阴离子交换柱。 对于使用碳酸盐/碳酸氢盐淋洗液进行的无机阴离子快速分离,建议使用 Dionex IonPac AS22 快速交换柱。
快速分离多种基质中的无机阴离子
可按照美国 EPA 方法 300.0 (A) 进行饮用水中常见阴离子的合规监测
可在 8 分钟内 (3 x 150mm 规格) 或 13 分钟内 (4 x 250mm 规格) 分离出多种样品基质中的常见无机阴离子
优异的氟化物保留和定量分析能力
可兼容氢氧化钠或氢氧化钾梯度洗脱,优化难度较高的分离
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清洁。
为应用的灵活性,提供多种规格可选
4 x 250 mm、3 x 150 mm 分析柱
4 x 50 mm、3 x 30 mm 保护柱
较长的 250 mm 柱可实现复杂样品基质的更高分辨率分离
较短的 150 mm 柱可实现相对干净基质的更快处理
内径较小的柱,可提高质量灵敏度,节省淋洗液和试剂,并降低运行成本
注: 要实现简单准确的淋洗液制备,请将 Dionex IonPac AS14 浓缩淋洗液和 7 种阴离子标准品组合装配合使用。

The IonPac? AS14A anion-exchange column is a carbonate-based column for fast analysis of the common inorganic anions in diverse sample matrices. The AS14A meets the performance requirements specified in US EPA Method 300.0 (A).
High efficiency and fast analysis (8 minutes)
High-capacity applications (13 minute run time)
Improved peak shape, efficiency, and pH stability
Meets or exceeds US EPA Method 300.0 (A) performance requirements
Simplified operation with AS14A Eluent Concentrate and Combined Seven Anion Standard
The AS14A is designed for the separation of inorganic anions, including fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate, using a carbonate/bicarbonate eluent coupled with suppressed conductivity detection. The inorganic anions can easily be determined in drinking water, wastewater, foods and beverages, scrubber solutions, and other diverse sample matrices.
For simplified operation use the AS14A with AS14A Eluent Concentrate and the Combined Seven Anion Standard. Use the ASRS 300 suppressor with the AS14A column for low-noise operation.
Note: See also the IonPac AS22, the newest carbonate eluent column recommended for fast analysis of inorganic anions.
