EC HPLC column (analytical), NUCLEODUR 100-5 CN-RP, 5 µm, 150x4.6 mm 5190-8376 Stability: 2-100 ppb levels stableThe 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
