EC HPLC column (analytical), NUCLEODUR 100-3 CN-RP, 3 µm, 50x2 mm 9301-0978 Re Containing Samples (Preparation &The endcapped cyanopropyl phase is based on high purity NUCLEODUR silica gel. This HPLC phase is able to generate a clearly recognizable different retention behavior compared to purely alkyl functionalized surface modifications. The polarity can be classified as intermediate based on multiple retention mechanisms such as dipole dipole, , and also hydrophobic interactions. Therefore, this phase shows a distinct selectivity for polar organic compounds
