Scope

This Standard specifies the method for determination of residual acrylonitrile
monomer in acrylonitrile - styrene copolymers (AS) and acrylonitrile-butadiene-
styrene copolymers (ABS) by headspace gas chromatography (HP-GC).
This Standard is applicable to the determination of residual acrylonitrile
monomer in acrylonitrile-styrene, acrylonitrile-butadiene-styrene resins and
their products, and the determination of residual acrylonitrile monomer in
rubber-modified acrylonitrile-butadiene-styrene resins and their products.
The detection limits of this method. Nitrogen-Phosphorus Detector method
(NPD) is 0.5 mg/kg; Flame Ionization Detector method (FID) is 2.0 mg/kg.
The First Method. Gas Chromatography Nitrogen-
Phosphorus Detector method (NPD)
