InPac AS24 陰離子交換色譜柱 The IonPac® AS24 是一款氫氧根體系陰離子交換色譜柱,用來分析飲用水中的鹵代乙酸,,離子色譜與質(zhì)譜和質(zhì)譜/質(zhì)譜檢測器聯(lián)用,。該色譜柱容量和選擇性能分析低于µg/L 級別濃度飲用水中的鹵代乙酸. 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
