The flexibility of β-content, γ-confidence tolerance intervals to qualimetry a simultaneous 22 aromatic amines derived from azo dyes in the fabric using a sensitive GC-MS technique.

An efficient GC-MS technique for the simultaneous determination of 22 azo amines in a textile matrix has been completed. Analytical validation using a new strategy based on the uncertainty concept is reported, uncertainty associated to measurement results was estimated and the applicability of our approach to the GC-MS method is investigated.
