%X Subwindow factor analysis(SWFA) has been proven to be an effective data processing technique. In this paper, it is applied to the resolution of overlapping GC-MS peaks. A two-component sample of azobiphenyl dyes (3,3'-dichlorobenzidine, 4,4'-methylene-bis-(2-chloroaniline)) was prepared and a data set from a mixture of azobiphenyl dyes recorded by GC-MS was obtained. Then the overlapping GC-MS data were resolved by SWFA. The results show that both mass spectrum and chromatogram of components can be resolved from multicomponent overlapping data. The resolved spectra were in good consistence with the mass spectra of standard samples. At the same time, overlapping GC-MS data were also resolved by WFA. In Comparing with WFA technique, SWFA is more convenient, and the speed of resolution could be increased.
