Abstract: A high-speed GC-MS method was developed for the analysis of carcinogenic aryl amines derived from reductive cleavage of certain azo dyes using the Rxi-35Sil MS column. The use of azo dyes that break down to form these amines in clothing is a potential exposure risk and is regulated in the European Union (EU) under the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation instated by (EC) 1907/2006. Additionally, certification under OEKO-TEX Standard 100 requires textiles to comply with (EC) 1907/2006. The optimal selectivity, high efficiency, and inertness of the Rxi-35Sil MS column make it an ideal choice for high-throughput GC-MS analysis of trace-level aryl amines.
