Dionex IonPac AS22-Fast 陰離子交換柱
Thermo Scientific? Dionex? IonPac? AS22-Fast 柱專為符合美國(guó) EPA 方法 300.0 (A) 的無(wú)機(jī)陰離子合規(guī)監(jiān)測(cè)而設(shè)計(jì)，且結(jié)合了 Dionex IonPac AS22 柱的選擇性和超快分離時(shí)間。 利用 Dionex IonPac AS22-Fast 柱，您可以快速、輕松地分離多種樣品基質(zhì)（包括飲用水、廢水、工藝液流和洗滌液）中的常見(jiàn)無(wú)機(jī)陰離子。
描述
各種基質(zhì)中無(wú)機(jī)陰離子和低分子量有機(jī)酸的超快速分析
按照美國(guó) EPA 方法 300.0 (A) 所述，對(duì)飲用水中的常見(jiàn)陰離子進(jìn)行合規(guī)監(jiān)測(cè)
在 5 分鐘內(nèi)對(duì)各種基質(zhì)（如飲用水、地表水、地下水和廢水）中的常見(jiàn)無(wú)機(jī)陰離子進(jìn)行超快速等度分離
即使使用短柱，容量仍足以維持分辨率，從而有助于實(shí)驗(yàn)室實(shí)現(xiàn)更高的生產(chǎn)率并增加通量
碳酸鹽峰與常見(jiàn)無(wú)機(jī)陰離子峰之間的出色分辨率
使用碳酸鹽/碳酸氫鹽淋洗液，是 Dionex IonPac AS4A-SC、AS12A、AS14、AS14A 和 AS22 無(wú)機(jī)陰離子應(yīng)用的更快替代選項(xiàng)。
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
4x150mm、2x150mm 分析柱
4x30mm、2x30mm 保護(hù)柱
較短的 150 mm 柱可實(shí)現(xiàn)相對(duì)干凈基質(zhì)的更快處理
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
注： 要實(shí)現(xiàn)簡(jiǎn)單準(zhǔn)確的洗脫液制備，請(qǐng)使用 Dionex IonPac AS22 濃縮洗脫液。

Super Fast Analysis of Common Inorganic Anions
Designed specifically for compliance monitoring of inorganic anions in accordance with US EPA Method 300.0 (A) and 300.1, the IonPac? AS22-Fast represents the culmination of more than 20 years of column development, and is a key complement to our award-winning Reagent-Free? IC system.
Super-Fast isocratic separation of the common inorganic anions in under 5 minutes
Carbonate peak well-resolved from the common inorganic anions
Same selectivity as AS22 column
Meets performance requirements specified in US EPA Method 300.0 (A)
Fast alternative for AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications
Simple, accurate eluent preparation with the AS22 Eluent Concentrate
Optimized for a 30 °C operating temperature to ensure reproducible retention times
The AS22-Fast is designed for the fast determination of inorganic anions and low molecular weight organic acids including fluoride, acetate, formate, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. The AS22-Fast can be used with isocratic carbonate/bicarbonate eluents and suppressed conductivity detection. Common inorganic anions can easily be separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
The AS22-Fast can be used in combination with the Eluent Generator and the Electrolytic pH Modifier (EPM) which automatically produce potassium carbonate/bicarbonate eluents from water. The AS22-Fast column is the newest carbonate eluent column recommended for super fast analysis of inorganic anions and is a faster alternative, using carbonate-bicarbonate eluents, for AS4A-SC, AS12A, AS14, AS14A, and AS22 inorganic anion applications.
Note: Use the Anion Self-Regenerating Suppressor (ASRS? 300) with the AS22-Fast column for eluent suppression.
