A high performance liquid chromatography- mass spectrometric method(HPLC-MS) has been developed for the simultaneous determination of six sensitizing disperse dyes in textile.The sample was extracted by methanol and determined by high performance liquid chromatography electrospray ionization mass spectrometry. The results indicated that the method is easier,faster and more sensitive. The linear range was 1 mg·L~(-1) to 100 mg·L~(-1).
