Dionex IonPac AS23 陰離子交換柱 064149
利用 Thermo Scientific? Dionex? IonPac? AS23 碳酸鹽淋洗液陰離子交換柱測定飲用水、地下水、廢水和其他多種樣品基質中的痕量溴酸鹽和其他鹵氧化物。 該款色譜柱專為測定飲用水基質中的痕量溴酸鹽（一種臭氧消毒的毒性副產物）設計，推薦用于此用途。 該款色譜柱的高容量和選擇性有助于在存在高濃度氯化物、硫酸鹽和碳酸鹽的情況下測定飲用水中低 μg/L 水平的溴酸鹽。 Dionex IonPac AS23 柱符合美國 EPA 方法 300.0 和 300.1 的性能要求。
描述
飲用水中的痕量溴酸鹽分析
按照美國 EPA 方法 300.0 和 300.1 進行飲用水中常見陰離子和鹵氧化物的合規監測
使用等度碳酸鹽/碳酸氫鹽淋洗液以及抑制型電導檢測，輕松對飲用水基質中的痕量溴酸鹽進行分析
選擇性得到優化，確保在存在超高濃度氯化物、硫酸鹽和碳酸鹽的情況下對溴酸鹽實現低 ppb 水平的測定
對飲用水、地下水、廢水和其他各種樣品基質中的鹵氧化物和常見無機陰離子進行分離
高容量，無需進行樣品預處理或預濃縮即可分析大多數飲用水
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柱清洗
更低的淋洗液要求，降低運行成本
由于使用相同的填料，Dionex IonPac AS23 毛細管柱提供的性能與標準孔和微孔 Dionex IonPac AS23 柱相同。 由于毛細管系統運行的淋洗液流速僅為標準孔系統的 1%，需要的淋洗液更少，產生的廢液也更少，從而降低了運行成本。
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
0.4x250mm 毛細管柱、0.4x50mm 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
更小柱內徑，提高質量靈敏度，節省洗脫液和試劑，并且降低運行成本
注： 要實現簡單準確的淋洗液制備，請使用 Dionex IonPac AS23 濃縮淋洗液。

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.
