TSKgel Octyl-80Ts has a lower carbon load and hydrophobicity than the corresponding ODS products. The C8 alkyl ligand provides a unique selectivity for the analysis of low MW pharmaceuticals, bases, nucleosides and nucleotides. Featuring high purity, metal free silica and a proprietary technique for complete endcapping of residual silanol groups, TSKgel Octyl-80Ts columns reduce tailing when analyzing basic compounds. Common applications include purity checks and peptide mapping.
相比ODS产品,TSKgel Octyl-80Ts 具有更低数的碳和更弱的疏水性。C8烷基配体提供了独特的选择性,来分析低分子量的药物、碱性物质、核苷和核苷酸。高纯度、不含金属的硅胶和一个独特的完整残余硅羟基封端技术,在分析碱性物质时,TSKgel Octyl-80Ts柱减少了拖尾。一般的应用包括纯度检验和肽图谱(peptide mapping)。
Bonded phase pore size is indicated by the number in the product description, in this case TSKgel Octyl-80Ts has 80Å nominal pore size. The pore size of the base silica is 100Å.
在产品描述中的数字指示了键合相孔径标,在这里TSKgel Octyl-80Ts 有80Å的标称孔径,硅胶基质材料的孔径尺寸为100Å。

优点
关于:ODS-80Tm、ODS-80Ts、Octyl-80Ts、CN-80Ts的区别
(1)ODS-80Tm,通用柱,适用于:
药物分析
碱性化合物
核酸片断
(2)ODS-80Ts
完全封端处理使TSKgel ODS-80Ts特别适用于强碱性化合物和pH=7.5条件下的操作应用。
(3)Octyl-80Ts
化学动力学比ODS更快,但疏水选择性更低。
(4)CN-80Ts
极性化合物分析中的ODS和辛基柱的替代柱。
