NUCLEOSIL C6H5
Nucleosil C6H5适合分析反相或离子对色谱分析中等级性的化合物
Nucleosil 高性能硅胶,特殊技术键合,使C6H5键合相在水相介质中稳定不流失,保证柱子长寿命
C6H5 的极性与C8相近,但对于多环芳烃、极性芳香类化合物、脂肪酸具有更好选择性
NUCLEOSIL? C6H5 | |
Phenyl modified silica phases for HPLC | |
not endcapped · 8 % C · USP L11 |
Relatively nonpolar phases for RP and ion pairing chromatography Available pore sizes 100, 120, 300, 500 and 1000 ?, available particle sizes 5 μm and 7 μm, Polarity similar to C8, but with different selectivity for polycyclic aromatic hydrocarbons, polar aromatics, fatty acids etc. Separation mechanism based on π–π interactions and hydrophobic (van der Waals) interactions, some residual silanol interactions | |
