    Application Note 360Rapid Determination of Azo Dyes in Textiles Using ASE and HPLC with MS and UV DetectionIntroductIonAzo dyes are used widely in the manufacture of various consumer goods such as leather, textiles, plastics, paper, hair care products, and cosmetics.On September 11, 2003, the European Union enacted European Parliament Directive 2006/61/EC, prohibiting the manufacture and sale of consumer goods containing certain aromatic amines originating from specifc azo dyes.1 The dyes named in this directive can, under certain conditions, be reduced to aromatic amines. Twenty two aromatic amines are currently classifed as carcinogenic or potentially carcinogenic to humans and are prohibited by the directive.Current sample preparation and analysis methods for these compounds are time consuming and labor intensive. Using accelerated solvent extraction (ASE®) with UltiMate 3000 HPLC/MS/UV analysis has proven to be a more advantageous alternative compared to other products currently available.ASE is a product for extracting organic compounds from solid or semisolid samples using conventional solvents at elevated temperatures and pressures. This application note describes methods for extraction of textile samples using ASE, along with the analytical methods for determination of 22 aromatic amines, some of which are specifed in the Parliament Directive.
