Chromegabond® WR (Wide Range)

Chromegabond® WR (Wide Range)


  1. 可用于分析碱性和酸性化合物
  2. 采用ES专利封端技术去活
  3. 以C8 和C18为固定相
  4. 填装3或5微米填料




Chromegabond WR 通过两步进行高碱去活。第一步是键合C8或者C18烷基链于合成的超高纯球形硅胶,第二步采用ES专利技术的多封端进行高碱去活。这种艺术级的键合方法利用C2或者C4的硅烷与硅烷醇进行反应。与传统的TMS封端不同,这种C2和C4封端产品能有效防止酸碱性条件下的水解。Chromegabond WR色谱柱pH适用范围为2 – 8。作为特殊键合处理的产品,Chromegabond WR具有高疏水性,并且对于酸碱化合物都非常惰性。对于分离含有疏水基团的极性化合物具有很好的效果。3微米的Chromegabond WR柱子分离效率很高,理论塔板数在160,000 to 170,000 plates/meter之间。C8和C18的柱子采用的都是相同的超纯硅胶。
