Dionex IonPac AS22 阴离子交换柱
Thermo Scientific? Dionex? IonPac? AS22 分析和保护柱 专为满足美国 EPA 方法 300.0 (A) 的无机阴离子合规监测而设计，可进行饮用水、地下水和废水的快速分析。 利用 Dionex IonPac AS22 柱，使用简单的等度碳酸盐/碳酸氢盐洗脱液，可以快速分离各种样品基质（包括饮用水、废水、工艺液流和洗涤液）中的常见无机阴离子。
各种基质中常见无机阴离子和低分子质量有机酸的分析
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
在 8 分钟内实现简单基质中常见无机阴离子的快速等度分离。
在 12 分钟内实现复杂基质中常见无机阴离子的等度分离。
对水浸中的氟化物进行出色保留以及对氟化物、乙酸盐和甲酸盐进行分解
碳酸盐峰与常见无机阴离子峰之间的出色分辨率
使用碳酸盐/碳酸氢盐洗脱液，是 IonPac AS4A-SC、AS12A、AS14 和 AS14A 无机阴离子应用的理想替代选项。
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。
更低的洗脱液要求，降低运行成本
由于使用相同的填料，因此 IonPac AS22 毛细管柱提供的性能与标准孔和微孔 IonPac AS22 柱相同。 由于毛细管系统运行的洗脱液流速仅为标准孔系统的 1%，需要的洗脱液更少，产生的废物也更少，从而降低运行成本。
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
0.4x250 mm 毛细管柱、0.4x50 mm 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
更小内径的柱，提高质量灵敏度，节省洗脱液和试剂，并且降低运行成本
注： 要实现简单准确的洗脱液制备，请使用 Dionex IonPac AS22 浓缩洗脱液。

Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Method 300.0 (A) and 300.1, the Thermo Scientific? Dionex? IonPac? AS22 column represents the culmination of more than 20 years of column development, and is a key complement to our award-winning Reagent-Free? IC (RFIC?) system. And now the Dionex IonPac AS22 column is available in capillary format. The Dionex IonPac AS22 Capillary column 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.
Fast isocratic separation of the common inorganic anions in 8 minutes
Isocratic separation of inorganic anions in complex sample matrices in 12 minutes
Carbonate peak well-resolved from the common inorganic anions
Meets performance requirements specified in U.S. EPA Method 300.0 (A)
Ideal alternative for Dionex IonPac AS4A-SC, AS12A, AS14, and AS14A inorganic anion applications
Simple, accurate eluent preparation with the Dionex IonPac AS22 Eluent Concentrate
Optimized for a 30 °C operating temperature to ensure reproducible retention times
The Dionex IonPac AS22 column is designed for the determination of inorganic anions and low molecular weight organic acids including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. The Dionex IonPac AS22 column can be used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection. Common inorganic anions can easily be separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
The Dionex IonPac AS22 column can be used in combination with the Eluent Generator and the Electrolytic pH Modifier (EPM) which automatically produce potassium carbonate/bicarbonate eluents from water. The Dionex IonPac AS22 column is the newest carbonate eluent column recommended for fast analysis of inorganic anions and is an ideal alternative, using carbonate-bicarbonate eluents, for Dionex IonPac AS4A-SC, AS12A, AS14, and AS14A inorganic anion applications.
Note: Use the Thermo Scientific Dionex ASRS 300 Anion Self-Regenerating Suppressor with the Dionex IonPac AS22 column for eluent suppression.
