摘要: A chemometric method to determine selective ion by using non-negative immune algorithm (NNIA) was proposed. In the method, mutual projections of chromatographic profiles at different m/z channel are calculated NNIA. Suppose a GC-MS data with m retention time points and n mass channels, onto profile will form spectrum 1×n vector. If is used, extracted be correct one. Therefore, comparing reference spectrum, can identified, corresponding obtained same time. 40-pesticide mixture investigated method. The results show that both spectral information interested components from overlapping signals, except for special cases isomeric very similar spectra.
