| Abstract: | The differences of the test results of banned AZO dyes by gas chromatography/mass spectrometry （GC/MS） and high performance liquid chromatography （HPLC） on denim were analyzed. The false positive reason of the o-tuluidine on denim by GC/MS was analyzed and discussed. An identification method of positive result of o-toluidine on denim by the fragment ion abundance ratio was proposed, which can effectively improve the qualitative result. |
