Screening of Agricultural Products for Pesticide Residues using GCMS-QP2010 in Full-Scan Mode, GCMSsolution software and Shimadzu Pesticides Mass Spectral Library

GCMS is commonly used for screening of agricultural products for the presence of pesticide residues. Electron impact ionization (EI) combined with Full Scan acquisition is good for identification of a compound because the ionization produces an extensive fragmentation for most organic compounds, which in turn gives a characteristic mass spectrum for the compund analysed. However, extensive frag mentation in EI mode and the complexity of the sample matrix (i.e the presence of many other compounds in the vegetable samples) also result in chromatogram which can easily contain more than 100 peaks. GSMSsolution software (Ver. 2) offers a solution to the problem through its Compound Finder. An example of the application of Compond Finder is illustrated in this report.
