scope:
NEN-EN-ISO 18218-1 is a method for determining ethoxylated alkylphenols (nonyphenol ethoxylate [NPEOn with 1 ≤ n ≤ 16] and octylphenol ethoxylate [OPEOn with 1 ≤ n ≤ 16]) in leather. This direct method is especially suitable where a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols. This method requires the use of high-performance liquid chromatography (HPLC) with triple quadrupole mass spectrometer (MSMS) to identify and quantify the ethoxylated alkylphenols.
