Pigments and extenders — Identification and quantification of primary aromatic amines in organic pigments by high-performance liquid chromatography (HPLC)

Scope

This document specifies a test method for the simultaneous determination of primary aromatic amines (PAAs) in organic pigments using external reference standards. The separation, identification and quantification of PAAs are achieved by high performance liquid chromatography (HPLC) analysis with gradient elution and diode array detection (DAD) and/or mass spectrometry detection (MSD) after an extraction step.

This analytical procedure can be applied to all organic pigments. The method allows the determination of extractable PAA content including sulfonated PAAs.
