We want to develop EU requirement pesticides list for tea, fruits and vegetables. There are around 600 pesticides. Are there any pesticides mixtures which we can use for LCMSMS?

And also we are purchasing new LCMSMS and we choose Thermo Quantis LCMSMS. Which HPLC pump is most suitable for LCMSMS pesticides analysis, binary or vanquish quaternary pump? Can anyone help me to solve theses problems.
