Dionex IonPac AS9-HC 陰離子交換柱 051786
使用 Thermo Scientific? Dionex? IonPac? AS9-HC 中等容量碳酸鹽淋洗液陰離子交換柱分析飲用水中的痕量溴酸鹽。 Dionex IonPac AS9-HC 柱專為分析飲用水中的痕量溴酸鹽設(shè)計(jì)，是美國(guó) EPA 方法 300.1 和 317.0 的色譜柱。 然而，*進(jìn)的高容量 Dionex IonPac AS23 碳酸鹽淋洗液陰離子交換柱則推薦用于測(cè)定臭氧處理飲用水中鹵氧化物和無(wú)機(jī)陰離子，如痕量溴酸鹽。
描述
環(huán)境基質(zhì)中的無(wú)機(jī)陰離子和鹵氧化物分析
按照美國(guó) EPA 方法 300.1 和 317.0 進(jìn)行飲用水中常見陰離子和鹵氧化物的合規(guī)監(jiān)測(cè)
輕松對(duì)臭氧處理飲用水基質(zhì)中的痕量溴酸鹽 (5μg/L) 進(jìn)行等度分離
在高難度應(yīng)用中,如復(fù)雜樣品基質(zhì)中的痕量亞硝酸鹽分析,獲得出色的分析結(jié)果。
與 Dionex IonPac AS9-SC 柱選擇性相似，但是容量更大，對(duì)飲用水中痕量溴酸鹽的分離效果更佳
溶劑兼容性讓您在分析含有疏水成分的樣品后方便地進(jìn)行柱清洗
提供多種規(guī)格，實(shí)現(xiàn)應(yīng)用靈活性
4x250mm、2x250mm、0.4x250mm 分析柱
4x50mm、2x50mm、0.4x50mm 保護(hù)柱
更長(zhǎng)的 250 mm 柱，實(shí)現(xiàn)更復(fù)雜樣品基質(zhì)的更高分辨率分離
更小柱內(nèi)徑，提高質(zhì)量靈敏度，節(jié)省洗脫液和試劑，并且降低運(yùn)行成本

High-Capacity Column for the Analysis of Inorganic Anions and Oxyhalides Including Bromate
Specifically designed for trace bromate in drinking water, the Thermo Scientific? Dionex? IonPac? AS9-HC column 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 Dionex IonPac AS9-HC column is a high-capacity carbonate eluent anion-exchange column with selectivity similar to the Dionex IonPac AS9-SC column. The Dionex IonPac AS9-HC column also supports the analysis of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate. The Dionex IonPac AS9-HC column is specified in validated methods such as U.S. 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 Dionex IonPac AS9-HC column also offers good retention of fluoride out of the water dip. The column’s high capacity (190 μeq for 4 × 250 mm column) increases retention time to approximately 22 min. Use the Thermo Scientific Dionex Anion Electrolytically Regenerating Suppressor (AERS 500) with the Dionex IonPac AS9-HC column.
The Dionex IonPac AS9-HC column is offered in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm), and capillary (0.4 × 250 mm). The capillary format is packed with the same material as the equivalent standard bore version (providing the same performance as a 4 mm column), but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption with helps reduce the operating costs.
Note: The Thermo Scientific Dionex IonPac AS23 column is the newest carbonate eluent column recommended for the analysis of oxyhalides including bromate.
