Abstract:
      A qualitative and quantitative analysis of the accelerator DPG in vulcanizates was established by UPLC/Q-TOF MS，gradient elution with acetonitrile＋water（volume fraction of methanoic acid was 0.000 3） as mobile phase was applied，and ESI source and positive ion mode were used for mass-spectrometry. The results showed that，the standard curve of accelerator DPG solution had good linearity with the real value in the range of mass concentration from 1 to 1 000 ng·mL-1，R2 was 0.995，the detection limit was 0.01 ng·mL-1，and the recovery was 94.0%～100.5%.
