The IonPac AS9-HC 是一款碳酸盐体系高容量色谱柱，用于无机阴离子和卤氧离子的分析，该柱能用于饮用水中痕量溴酸盐检测。色谱柱性能符合U.S.EPA方法300.1和317要求。
High-capacity column for the analysis of inorganic anions and oxyhalides including bromate.
Specifically designed for trace bromate in drinking water, the AS9-HC is the specified column for U.S EPA Methods 300.1 and 317.0.
• For the analysis of oxyhalides and inorganic anions in complex sample matrices
• Simple, isocratic method for trace bromate (5 μg/L) in ozonated drinking water matrices
• Ideal for difficult applications, such as trace nitrite in complex sample matrices
• Improved separation of bromate/chloride, chloride/nitrite, chlorate/nitrate analyte pairs
The AS9-HC is a high-capacity carbonate eluent anion-exchange column with selectivity similar to the AS9-SC column. The AS9-HC also supports the analysis of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride,nitrite, bromide, chlorate, nitrate, phosphate, and sulfate. The AS9-HC is specified in validated methods such as US EPA Method 300.1 and 317.0 and meets or exceeds the performance requirements of these methods.
This column separates trace bromate in drinking water matrices using an isocratic carbonate eluent and a large-loop
injection. The AS9-HC also offers good retention of fluoride out of the water dip. The column’s high capacity (190 μeq for 4 × 250 mm) increases retention time to approximately 22 min. Use the Anion Self-Regenerating Suppressor (ASRS 300) with the AS9-HC column.
Note: The AS23 is the newest carbonate eluent column recommended for the analysis of oxyhalides including bromate.
