使用 Thermo Scien筆媽tific? Dionex? IonPac? AS24 分析柱和保護柱現道,可分離飲用水樣(yàng)品中的鹵乙酸和溴酸鹽。 這(zhè)都就種(zhǒng)高容量氫氧化物選擇性陰離子交低喝換柱專爲在質譜檢測前端,分離飲站有用水中的鹵乙酸和溴酸鹽而研制。 2x250mm 爲美國(guó) EPA 秒購方法 557 中的柱規格。 Dionex Io行一nPac AS24 的柱容量和選擇性能(néng)夠确保對(duì)飲用水火雪中的低至 μg/L (ppb)級 濃度鹵乙酸進(jìn)行分美麗析。 該柱也非常适合開(kāi)發(fā)特殊的從湖應用方法,能(néng)對(du朋妹ì)環境陰離子,包括複雜基質中水事無機陰離子、鹵氧化物、含氧陰離子學年和有機酸等實現分離。
色譜分析性能(néng)優異
美國(guó) EPA 方法 557 地計 (2x250mm)
高柱容量(140μeq/柱,2x250mm)使得進(jìn)樣(yàng)用兒複雜基質時(shí)不會(huì)出現色譜柱過(gu短老ò)載,同時(shí)又能(néng)始終對(duì)低濃度分析物友土獲得*的峰形
當測定高離子強度基質中的鹵乙酸時(shí機水),不需進(jìn)行樣(yàng)品預處理
可在美國(guó) EPA 方法 302.0 所述的關于溴酸鹽的 2D 方法錯現中用作第二維色譜柱(2x250 mm)
尤其适合在梯度洗脫下使用 Reagent北喝-Free? 離子色譜(RFIC?)系統開(kāi)發(fā)專門短是應用方法
可在環境溫度或更高溫度下運行;經(jīng)過(guò)優化選擇師小在 15oC 的操作溫度下可确保鹵乙酸的回收率具有雨吧良好(hǎo)重現性
與 HPLC 有機溶劑兼容,操作靈活、易于清洗
