Dionex IonPac AS22 陰離子交換柱 064141

Thermo Scientific? Dionex? IonPac? AS22 分析和保護柱 專為滿足美國 EPA 方法 300.0 (A) 的無機陰離子合規監測而設計，可進行飲用水、地下水和廢水的快速分析。 利用 Dionex IonPac AS22 柱，使用簡單的等度碳酸鹽/碳酸氫鹽洗脫液，可以快速分離各種樣品基質（包括飲用水、廢水、工藝液流和洗滌液）中的常見無機陰離子。

描述

各種基質中常見無機陰離子和低分子質量有機酸的分析

• 按照美國 EPA 方法 300.0 (A) 進行飲用水中常見陰離子的合規監測

• 在 8 分鐘內實現簡單基質中常見無機陰離子的快速等度分離。

• 在 12 分鐘內實現復雜基質中常見無機陰離子的等度分離。

• 對水浸中的氟化物進行出色保留以及對氟化物、乙酸鹽和甲酸鹽進行分解

• 碳酸鹽峰與常見無機陰離子峰之間的出色分辨率

• 使用碳酸鹽/碳酸氫鹽洗脫液，是 IonPac AS4A-SC、AS12A、AS14 和 AS14A 無機陰離子應用的理想替代選項。

• 溶劑兼容性讓您在分析含有疏水成分的樣品后方便地進行清潔。

更低的洗脫液要求，降低運行成本

由于使用相同的填料，因此 IonPac AS22 毛細管柱提供的性能與標準孔和微孔 IonPac AS22 柱相同。 由于毛細管系統運行的洗脫液流速僅為標準孔系統的 1%，需要的洗脫液更少，產生的廢物也更少，從而降低運行成本。

提供多種規格，實現應用靈活性

• 4x250 mm、2x250 mm 分析柱

• 4x50 mm、2x50 mm 保護柱

• 0.4x250 mm 毛細管柱、0.4x50 mm 毛細管保護柱

• 更長的 250 mm 柱，實現更復雜樣品基質的更高分辨率分離

• 更小內徑的柱，提高質量靈敏度，節省洗脫液和試劑，并且降低運行成本

注： 要實現簡單準確的洗脫液制備，請使用 Dionex IonPac AS22 濃縮洗脫液。

Dionex IonPac AS22 陰離子交換柱

Fast Analysis of Common Inorganic Anions

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.
