AN360: Rapid Determination of Azo Dyes in Textiles Using ASE and HPLC with MS and UV Detection

Instrument Type: HPLC

Azo dyes are used widely in the manufacture of various consumer goods such as leather, textiles, plastics, paper, hair care products, and cosmetics. The EU enacted European Parliament Directive 2006/61/EC, prohibiting the manufacture and sale of consumer goods containing certain aromatic amines originating from specific azo dyes. This application note describes methods for extraction of textile samples using ASE, along with the analytical methods for the determination of 22 aromatic amines, some of which are specified in the Parliament Directive.
