Deconvolution Overlapping Pesticides Gas Chromatography-Mass Spectrometry Using Auto Mass Deconvolution & Identification System(AMDIS)

Auto Mass Spectral Deconvolution & Identification System (AMDIS) was used to deconvolute four examples of overlapped pesticides. The shortcoming and advantage of AMDIS were analyzed. The results show there is a good result when the scan number difference of overlapped pesticide exceeded 1. This advantage will help to remove the interference through overlapping components each other, and confirm results more correctly. On the other hand, there are shortcomings such as missing non-characteristic ions and low detect ability.
