一般說明

Ascentis 系列色谱柱是 Supelco 科学家推出的第四代 HPLC 色谱柱技术。Ascentis 系列色谱柱是以高纯硅胶为基质,孔径 100Å,硅胶粒径为 3、5 和 10 微米。该色谱柱用于小分子的应用,柱内径可从微径柱(1.0mm 内径)扩展到制备尺寸(50mm 内径)。该系列包括 C18、C8、苯基、Si 和内嵌极性基团相(反相酰胺)。

Ascentis C8 色谱柱重现性好,对极性化合物具有优良的选择性。该键合相在高含水量的流动相和高有机相含量的流动相中均有优良的性能。

特點和優勢

  • 对疏水性分子的保留性极好
  • 峰形极佳
  • LC-MS 分离流失低
