產(chǎn)品介紹
Dionex IonPac AS9-SC 陰離子交換柱
用途和特點(diǎn)：
IonPac AS9-SC陰離子交換分離柱用CO32-/HCO3-作淋洗液，用于飲用水、地表水、廢水和其它各種樣品基體中的無機(jī)陰離子和鹵素含氧酸的等度淋洗、快速分離，包括：F-，ClO2-，BrO3-，Cl-，NO2-，Br-，ClO3-，NO3-，PO43-和SO42-等。有機(jī)溶劑可匹配性方便柱子的清洗。
IonPac AS9-HC是高容量陰離子交換分離柱，選擇性與IonPac AS9-SC相似，特別適用于飲用水消毒副產(chǎn)品—鹵素含氧酸和常見無機(jī)陰離子的分離?？筛纳艬rO3-/Cl-，Cl-/NO2-，和ClO3-/NO3-的分離。用碳酸鹽等度淋洗，直接進(jìn)樣，可測定典型飲用水中低至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.
