Target transformation factor analysis(TTFA) based on the actual most different spectra (AMDS) could resolute the pure component spectra. But it depended on the con-struction of primitive mixture greatly. The new method that AMDS were replaced by the cal-culated most different spectra(CMDS) overcome this restriction. It was applied in the simu-lated and actual systems and the results were satisfactory.
