Rapid quantitation of azo dyes in water and textiles by GC–TOF MS

This study describes the use of fast GC–TOF MS for high-throughput analysis of azo dye aromatic amines in textiles and water.

The method was used for the analysis of 26 aromatic amines using GC–TOF MS, resulting in a total run time of just seven minutes and detection limits <1 ng/mL. Unlike quadrupole MS, TOF detectors do not suffer from spectral skew, enabling more robust deconvolution of co-eluting analytes.
