COSMOSIL烷基色谱柱(C8、PE、CN)
COSMOSIL烷基柱还包括C22 (二十二烷基),C8(辛烷基),C4(丁基)和TMS(三甲基)等烷基键合固定相的烷基柱。根据各种填料的疏水性大小不同,保留时间依次为C22=C18>C8>C4>TMS。这些柱子的疏水性比C18柱或C22更低,能将高疏水性化合物和疏水性差别很大的化合物有效分离。C22的疏水性与C18大致相同。但是,C22的立体选择性高于C18柱,所以C22有更好的分离效果。
The COSMOSIL苯乙基(PE-MS)色谱柱和COSMOSIL 氰基色谱柱(CN-MS)提供另一种基于π-π 相互作用分离的选择。建议使用这些色谱柱当烷基固定相色谱柱不能很好分离类似化合物的时候。
