本文件规定了纺织品和纺织产品中可萃取烷基酚乙氧基化物（APEO）定性和定量分析的正相液相色谱（NPLC）分离方法。 该方法提供了几种用于测定烷基酚乙氧基化物（APEO）的仪器选项，如带质谱仪的正相液相色谱仪（NPLC/MS）、带荧光检测器的正相液相色谱仪（NPLC/FLD），带带电气溶胶检测器的正相液相色谱仪（NPLC/CAD）和带蒸发光散射检测器的正相液相色谱仪（NPLC/ELSD）。

This document specifies the normal phase liquid chromatography (NPLC) separation method for the qualitative and quantitative analysis of extractable alkylphenol ethoxylates (APEO) in textiles and textile products. This method provides several instrument options for the determination of alkylphenol ethoxylates (APEO) such as normal phase liquid chromatograph with mass spectrometer (NPLC/MS), normal phase liquid chromatograph with fluorescence detector (NPLC/FLD), normal phase liquid chromatograph with charged aerosol detector (NPLC/CAD) and normal phase liquid chromatograph with evaporative light scattering detector (NPLC/ELSD).
