Azo dyes are widely used due to their vibrant colors and compatibility with various substrates, but their reductive cleavage releases toxic aromatic amines. Existing quantification methods have limitations in applicability and simultaneous detection. This study presents a modified GC-MS method to analyze 28 amines and two internal standards in a single run, with UFLC confirmation. The method applies to diverse matrices, including liquid and powder dyes, textiles, and leather, eliminating the need for separate protocols. Recovery was 85%-115%, with linearity (R² = 0.994-0.996), a calibration r...
