General description
Dowex Retardion 11A8的两性特性允许从复杂混合物中特异性分离元素，这通常可以使用单官能离子交换剂。使用Retardion 11A8通过放射化学NAA测定痕量的锌和镉。
Retardion 11A8 并非真正的混合床树脂，而是带有混合官能团的树脂。它包含成对的阴离子和阳离子交换位置（每一个都作为另一个的反离子），能从料流中吸附移动的离子。
Application
Dowex Retardion 11A8用于固相萃取，通过火焰原子吸收光谱法测定总浓度。
离子分离的色谱树脂。用于去除蛋白质样品中的离子洗涤剂（如 SDS）。还能去除水溶液中的电解质以及分离阴阳离子。由于 SEC 类型的机制会发生脱盐，因此建议使用色谱柱来获得较好的结果。
Physical form
混合床
Other Notes
该离子交换树脂未经特殊处理或清洁。建议进行适当的初步洗脱和清洗处理。
