Introduction
This document specifies the normal phase liquid chromatography (NPLC) separation method for the
quantitative and qualitative analysis of extractable alkylphenol ethoxylates (APEO) in textile and
textile products. NPLC separation method enables alkylphenol ethoxylates to be analysed by high
performance liquid chromatograph (HPLC) with Mass Spectrometer (MS), fluorescence detector (FD),
charged aerosol detector (CAD) and evaporative light scattering detector (ELSD).
A study of the contribution percentage (mole fraction) of APEO congeners is presented in Annex D.
