Scope

This document specifies graphite furnace atomic absorption spectrometry and inductively coupled plasma mass spectrometry for the determination of iron and copper content in industrial acrylonitrile. The graphite furnace atomic absorption spectrometry in this document is suitable for the determination of 0.010mg/kg~1.000mg/kg iron and copper content in industrial acrylonitrile; the inductively coupled plasma mass spectrometry is suitable for the determination of 0.005mg/kg~ 1.000mg/kg Determination of iron and copper content.
