IonPac AS24 阴离子交换色谱柱 The IonPac® AS24 是一款氢氧根体系阴离子交换色谱柱，用来分析饮用水中的卤代乙酸，离子色谱最好与质谱和质谱/质谱检测器联用。该色谱柱容量和选择性能分析低于µg/L 级别浓度饮用水中的卤代乙酸. For separation of haloacetic acids and bromate in drinking water prior to MS or MS/MS detection
The IonPac AS24 hydroxide-selective anion-exchange column is specifically designed for haloacetic acids in drinking water prior to MS or MS/MS detection. The capacity and selectivity enables analysis of haloacetic acids in drinking water at low-μg/L concentrations. The AS24 column is the specified column in US EPA Method 553. • Specified column for US EPA Method 553 • High capacity: 140 μeq per column (2 × 250 mm) • Determine HAAs in high-ionic strength matrices without sample pretreatment • Column selectivity is optimized for a 15 ºC operating temperature • Compatible with HPLC organic solvents • Used as second dimension column in 2-D method for bromate in US EPA Method 302.0
