摘  要:
[Aims] The aims were to establish the qualitative and quantitative analysis method for herbicide by UPLC-Q-TOF. [Methods] The structural formula of herbicide was confirm by ultra performance liquid chromatographyquadrupole time of flight mass spectrometry(UPLC-Q-TOF), and the content of trifloxysulfuron was analyzed by liquid chromatography and UV detector. [Results] The herbicide of trifloxysulfuron was confirmed, and the content was 9.1%.[Conclusions] The UPLC-Q-TOF was applied for the discovery and identification of chemical compound. This work provides an effective idea and method for the qualitative ananysis of pesticide.
