Analysis of aromatic amines derived from Azo colorants using hydrogen as GC/MS carrier gas.
Azo dyes are extensively used in consumer products - including textiles, leather goods, clothing, and toys - with global demand measured in millions of tonnes annually. Because many azo dyes can release aromatic amines that are allergenic or carcinogenic, the European Union has restricted or banned those azo dyes capable of yielding any of the 14 aromatic amines classified as Category 1 or 2 carcinogens under Directive 76/769/EEC.
