Determination of Pesticides and Related Chemicals in Grains and Cereals

This book features a systematic study conducted regarding the mass spectrometric characteristics of GC-MS and LC-MS-MS and GPC behaviours characteristics for 858 pesticides, and a GC-MS analytical database was established for 541 pesticides, a LC-MS-MS analytical database for 629 pesticides and a GPC behavioural characteristic database for 751 pesticides. Under the GC-MS and LC-MS-MS optimised analytical conditions based on these database, a series of the comparison testes were completed. 486 pesticides and related chemicals in 5 kinds of grain samples such as wheat, barley, rice, maize and oats were pre-treated by ASE extraction and SPE cleanup as well as 465 pesticides were pre-treated by homogeneous and shaking extraction and GPC cleanup. A GC-MS analytical method has been established for determination of 475 pesticides in grains and cereals, and same as LC-MS-MS analytical method for determination of 372 pesticides and related chemicals.
