This paper selectes a C18 liquid chromatography column with short length,small diameter and small particle size for analysis using the methanol-water system mobile phase to establish a rapid ultra-performance liquid chromatography separation technique.This new ultra performance liquid chromatography method is capable of isolating 26 aromatic amines within 15.000 min,with the detection limit of 0.1-0.5 mg/kg at s/n of 3.Each aromatic amine has a good linear relationship(R2≥0.999 0)in 0.5-10.0 mg/kg,with a relative standard deviation(RSD)less than 1.500%.Compared with the standard liquid chromatography method of analyzing carcinogenic aromatic amines,it shortens the detection time while saving the amount of solvent used.In the process of daily textile testing,the work efficiency is improved and the cost is saved.
