A chromatographic analytical column, containing an agglomerated type anion-exchange packing, comprising:
Component A, which comprises a pressure packed bed of substrate particles of insoluble synthetic resin, having cation-exchanging sites at least on their available surfaces, the particles being of low porosity relative to Component B microparticles, and
Component B, derived by agglomerating microparticles of insoluble synthetic resin onto the pressure packed bed of Component A particles, the microparticles having a volume average diameter of less than 1,500 and greater than 50 Angstroms and having anion-exchanging sites, at least on their outer surfaces, which attract available cation sites of Component A, wherein said microparticies are attached as a monolayer to the available surfaces of the Component A particles.
一种含有团聚型阴离子交换填料的色谱分析柱,包括
A 组分,包括一个由不溶性合成树脂基质颗粒组成的压力填料床,这些颗粒至少在其可用表面上具有阳离子交换位点,相对于 B 组分的微颗粒,这些颗粒的孔隙率较低;以及
B 组分,通过将不溶性合成树脂微粒团聚到 A 组分颗粒的压力填料床上而得到,微粒的体积平均直径小于 1,500 埃,大于 50 埃,至少在其外表面具有阴离子交换位点,可吸引 A 组分的阳离子位点,其中所述微粒以单层形式附着在 A 组分颗粒的可用表面上。
