一般說明
Ascentis Express 5 μm RP-Amide是一款基于高效熔融核®颗粒设计的高速、高效液相色谱柱。熔融核颗粒提供了围绕固体二氧化硅核的高纯度二氧化硅薄多孔外壳。由于在0.6 μm厚的多孔外壳中的浅扩散途径和5 μm的高度均匀的总粒度，该颗粒设计表现出非常高的柱效。Ascentis Express 5 μm RP-Amide的一步键合、封端、酰胺基、极性嵌入固定相提供了稳定的反相填料，具有降低的疏水性。Ascentis Express RP-Amide可用于具有C18或C8正交选择性的碱性、酸性或中性化合物。极性包埋的Ascentis Express 5 μm RP-Amide色谱柱与100%水性流动相相容，不会出现“相崩溃”。
