Dionex IonPac AS14A 陰離子交換柱 056904
使用 Thermo Scientific? Dionex? IonPac? AS14A 碳酸鹽淋洗液陰離子交換柱，可實現對飲用水、廢水、食品和飲料、洗滌液等多種復雜基質中無機陰離子的快速等度分離。 Dionex IonPac AS14A 柱滿足或超出了美國 EPA 方法 300.0 (A) 的要求。 但是，對于無機陰離子的快速分析，建議使用*進的 Dionex IonPac AS22 碳酸鹽淋洗液陰離子交換柱。 對于使用碳酸鹽/碳酸氫鹽淋洗液進行的無機陰離子快速分離，建議使用 Dionex IonPac AS22 快速交換柱。
描述
快速分離多種基質中的無機陰離子
可按照美國 EPA 方法 300.0 (A) 進行飲用水中常見陰離子的合規監測
可在 8 分鐘內 (3 x 150mm 規格) 或 13 分鐘內 (4 x 250mm 規格) 分離出多種樣品基質中的常見無機陰離子
優異的氟化物保留和定量分析能力
可兼容氫氧化鈉或氫氧化鉀梯度洗脫，優化難度較高的分離
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。
為應用的靈活性，提供多種規格可選
4 x 250 mm、3 x 150 mm 分析柱
4 x 50 mm、3 x 30 mm 保護柱
較長的 250 mm 柱可實現復雜樣品基質的更高分辨率分離
較短的 150 mm 柱可實現相對干凈基質的更快處理
內徑較小的柱，可提高質量靈敏度，節省淋洗液和試劑，并降低運行成本
注： 要實現簡單準確的淋洗液制備，請將 Dionex IonPac AS14 濃縮淋洗液和 7 種陰離子標準品組合裝配合使用。

Fast Analysis of the Common Inorganic Anions in Diverse Sample Matrices
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.
