IonPac AS7 阴离子交换色谱柱
The IonPac® AS7 一是款高容量，高效，疏水性阴离子交换色谱柱。用于分离大范围价态阴离子，包括多磷酸盐, 聚磷酸酯, 和其他多价的复杂试剂如EDTA 和NTA。
For the 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 elution (eliminating metal interferences) with post-column
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.
