Perfluorotetradecanoic acid
What you’ll notice is that absolute concentrations are less important than the ratio of the interfering element to the element of interest

EC HPLC column (analytical), NUCLEOSIL 120-7 CN, 7 µm, 250x4 mm 548-3005 Perfluorotetradecanoic acidThe cyanopropyl 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, CN phases show a distinct selectivity for polar organic compounds as well as for molecules containing electron systems (e. g., analytes with
