Dionex IonPac AS9-SC 阴离子交换柱



用途和特点:
IonPac AS9-SC阴离子交换分离柱用CO32-/HCO3-作淋洗液,用于饮用水、地表水、废水和其它各种样品基体中的无机阴离子和卤素含氧酸的等度淋洗、快速分离,包括:F-,ClO2-,BrO3-,Cl-,NO2-,Br-,ClO3-,NO3-,PO43-和SO42-等。有机溶剂可匹配性方便柱子的清洗。
IonPac AS9-HC是高容量阴离子交换分离柱,选择性与IonPac AS9-SC相似,特别适用于饮用水消毒副产品—卤素含氧酸和常见无机阴离子的分离。可改善BrO3-/Cl-,Cl-/NO2-,和ClO3-/NO3-的分离。用碳酸盐等度淋洗,直接进样,可测定典型饮用水中低至5ug/L的BrO3-。

For the Fast Isocratic Separation of Inorganic Anions and Oxyhalides

The IonPac? AS9-SC is designed for the isocratic separation of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, wastewater, groundwater, and other diverse sample matrices.

  • For fast analysis of oxyhalides and inorganic anions at similar concentrations

  • Ideal for simple sample matrices

Common inorganic anions and oxyhalides can be determined in less than 10 minutes using an isocratic carbonate/bicarbonate eluent coupled with suppressed conductivity detection.

The IonPac AS9-SC column is specified in US EPA Method 300.0 (B), and meets or exceeds the performance requirements of this method. Use the Anion Self-Regenerating Suppressor (ASRS? 300) with the IonPac AS9-SC column.

Note: See also the IonPac AS23, the recommended column for the analysis of oxyhalides, including bromate.
