Based on the algorithm of stochastic resonance, a new method improved the signal-to-noise ratio (SNR) of weak chromatography signal remarkably. An excellent quantitative relationship can be obtained between concentration and weak chromatography signals of Sudan I which was embedded in the noise background. © 2006 Elsevier B.V.
