            Dionex IonPac AS7 Column 陰離子交換填充柱

            簡要描述:

            戴安公司生產(chǎn)的儀器主要有離子色譜儀、高效液相色譜儀、快速溶劑萃取儀和氨基酸直接分析儀。其中離子色譜儀憑借著雄厚的技術(shù)優(yōu)勢和方法已廣泛地應(yīng)用于各個領(lǐng)域,其*達(dá)80%。與離子色譜相關(guān)的文章有90%均出自戴安公司生產(chǎn)的離子色譜儀。   
            戴安公司的快速溶劑萃取儀15分鐘之內(nèi)僅用15毫升溶劑既可完成對10g樣品的萃取,該技術(shù)已在環(huán)境、藥物、食品和聚合物工業(yè)等領(lǐng)域得到廣泛應(yīng)用。

            IonPac AS7 Specialty Anion-Exchange Column

            For Separation of a Wide Range of Polyvalent Anions

            The IonPac? AS7 separates a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, and other polyvalent complexing agents such as EDTA and NTA using acidic eluent (eliminating metal interferences) with postcolumn derivatization and UV-Vis detection.

            • For polyvalent anions and chelating agents in complex sample matrices
            • Determines cyanide and sulfide using amperometric detection
            • Useful for hexavalent chromium in environmental matrices

            The AS7 column has a unique polymer packing that provides superior performance for separating ionic and polar compounds. The patented packing offers high speed, high efficiency, and high loading capacity at moderate backpressures.

            Note: The newer IonPac AS16 or AS20 column is recommended for polyphosphates.
