利用 Thermo Scientific? Dionex? I又車onPac? AS23 碳酸鹽淋洗液陰離子交換柱測定飲用水、地答務下水、廢水和其他多種(zhǒng)樣(yàng)品基質中的科低痕量溴酸鹽和其他鹵氧化物。 該款色譜柱專爲測定飲林資用水基質中的痕量溴酸鹽(一種(zhǒng)臭氧消很讀毒的毒性副産物)設計,推薦用于愛風此用途。 該款色譜柱的高容量和選擇性有助于在存黑遠在高濃度氯化物、硫酸鹽和碳酸鹽的情況下測定飲用水中低 μg/L 水平的溴酸黑民鹽。 Dionex IonPac AS23 柱符合美國(guó)雨問 EPA 方法 300.0 和 300.1 的性能(néng)分高要求。
描述
飲用水中的痕量溴酸鹽分析
按照美國(guó) EPA 方法 300.0 和 300.1 進(jìn)行飲議哥用水中常見陰離子和鹵氧化物的合規監測
使用等度碳酸鹽/碳酸氫鹽淋洗液以及抑制型電西他導檢測,輕松對(duì)飲用水基質中的痕量溴酸鹽進(jì土民n)行分析
選擇性得到優化,确保在存在超高濃度弟計氯化物、硫酸鹽和碳酸鹽的情況下對(duì)溴酸鹽靜河實現低 ppb 水平的測定
對(duì)飲用水、地下水、廢水和其他各種(zhǒng)樣(yà線國ng)品基質中的鹵氧化物和常見無機陰離子進(jì器暗n)行分離
高容量,無需進(jìn)行樣(yàng)品預處理或預濃縮即可分析大多數飲用水
溶劑兼容性讓您在分析含有疏水成(chéng)分的樣(yàng)品後(hòu費在)方便地進(jìn)行柱清洗
更低的淋洗液要求,降低運行成(chén吃關g)本
由于使用相同的填料,Dionex IonPac AS23 毛細管柱提供的道相性能(néng)與标準孔和微孔 Dionex I月木onPac AS23 柱相同。 由于毛細管系統運行的淋洗液流速僅爲标是女準孔系統的 1%,需要的淋洗液更少,産生的廢液也更少,從而降低了運行成(ché我作ng)本。
提供多種(zhǒng)規格,實現應用靈活性
4x250 mm、2x250 mm 分析柱
4x50 mm、2x50 mm 保護河煙柱
0.4x250mm 毛細管柱、0.4x50mm 毛事看細管保護柱
更長(cháng)的 250 mm 柱,實現更複雜樣(yàng)品基科聽質的更高分辨率分離
更小柱内徑,提高質量靈敏度,節省洗脫液和試劑,并且降低年少運行成(chéng)本
注: 要實現簡單準确的淋洗液制備,請使用 Dionex說文 IonPac AS23 濃縮淋洗液。
