A Multi-Component Stochastic Resonance Algorithm That Can Be Used to Detect Multiple Weak Chromatographic Peaks Simultaneously

摘要

A new stochastic resonance algorithm based on the method of energy gain was developed by introduce an external energy field upon the chromatographic signals in order to simultaneously amplify and detect weak peaks from multi-component. The experimental weak chromatographic peaks from Para Red and Sudan I ~ IV were analyzed using the new algorithm. It was suggested that the proposed algorithm might avoid depressing the peak from the component with low concentration or weak chromatographic response. The weak chromatographic peaks from the samples with different concentrations were all amplified significantly. It is expected that multi-component stochastic resonance algorithm will play an important role in the rapid analysis of complex samples, such as multi-residue analysis and detection of TCM trace active substances.
