| 中文摘要: |
| 利用超高效液相色谱-串联四极杆飞行时间质谱法，以乙腈＋水（含体积分数为0.000 3的甲酸）为流动相进行梯度洗脱，采用ESI正离子模式，对硫化胶中促进剂DPG进行定性定量分析。结果表明，在质量浓度为1～1 000 ng·mL-1范围内，促进剂DPG溶液标准曲线线性关系良好，相关因数为0.993，检出限为0.01 ng·mL-1，回收率为94.0%～100.5%。 |
| 英文摘要: |
| 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%. |
