①How to realize electronization for pesticide analytical techniques? Foreword With the rapid development of 21st century’s informatization technology, the world has already entered into the internet age and the prospect of pesticide residue analytical technique faces Three Major Challenges: ①How to realize electronization for pesticide analytical techniques? ②How to realize automation for the generation of the report of pesticide residue big data? ③How to realize visualization for pesticide residues risk source tracing? 随着21世纪信息化技术快速发展,世界已进入互联网时代,农药残留检测技术如何发展,面临三大挑战: ①农药残留检测如何实现电子化? ②农药残留大数据报告生成如何实现自动化? ③农药残留风险溯源如何实现视频化?
Challenge No.1: How to realize electronization for pesticide residue detection? Solution: Pesticide residue qualitative identification is conducted with electronic references taking place of substantial references, which may realize electronization for pesticide residue qualitative identification. 1 挑战之一:农药残留检测如何实现电子化? 解决方案:农药残留定性鉴定以电子标准取代实物标准,可以实现农药残留鉴定电子化。
1.1Establishment of HRMS (GC-Q-TOFMS and LC-Q-TOFMS) accurate mass database and spectra library for 1200 world commonly used pesticides, laying a theoretical and methodological foundation for development of non-target detection technology Accurate mass database is used for TOFMS screening and spectra is used for QTOFMS confirmation of target pesticides, which has laid a theoretical and methodological foundation for non-target pesticide residue detection techniques. 用两种HRMS(LC-Q-TOFMS和GC-Q-TOFMS)技术评价了各种不同条件下1200多种农药的质谱特征,建立 了一级和二级精确质量数据库和谱图库
Major elements of electronic identity card for each pesticide 1.2 Electronic references developed for over 1200 pesticides to replace substantial references A unique electronic identity card (electronic identification references) is developed for each of the 1200-plus pesticides, making the identification method of using electronic references to replace the conventional pesticide substantial references as comparison come true and causing the non-target pesticide residue analytical technique to realize a frog-leap development. ①Retention time ②accurate mass of primary adduct ions ③isotope distribution ④isotope abundance ⑤ spectra library Major elements of electronic identity card for each pesticide 为1200多种农药的每一种都建立了自身独有的电子身份证,从而实现了以电子身份证代替传统的实物标准做参比的定性方法,实现了农药残留由靶向检测向非靶向筛查的跨越式发展。
1.3 Development of high throughput and high resolution GC-Q-TOFMS and LC-Q-TOFMS techniques for pesticide residues LC-QTOF 544 Compounds ① 239 pesticides GC-QTOF 722 Compounds ①242 pesticides ②209 PCBs ③271 pesticides Simultaneous determination of 1200 pesticides using both techniques with a single sample preparation Reference materials as comparison have been eliminated and accurate mass is used for identification, thus saving resources, reducing pollutions, improving the analytical speed and satisfying fully the requirements for green development, environmentally-friendliness, cleanliness and high efficiency. 从而建立了一次样品制备,LC-Q-TOFMS一次可检测544种农药;GC-Q-TOFMS可检测722种农药,两项技术共同检测的农药超过1200多种。实现了高速度、高通量、高精度、高可靠性和高度信息化和自动化,也实现了电子化。
Challenge No.2: how to realize automation for the generation of the report of pesticide residue detection big data? Solutions: HRMS+ Internet+Intelligent Analysis tri-element merged technique may realize automatic generation of the big data report of pesticide residues. 2 挑战之二:农药残留检测技术大数据报告生成如何实现自动化 解决方案:HRMS+互联网+智能分析三元融合技术可以实现农药残留大数据报告生成自动化
