Abstract: The phenomena of overlapping chromatographic peaks may make the qualitative and quantitative analysis of the chemical composition become difficult. Although the wavelet transform can make a better separation on overlapping peaks by using its multi resolution characteristics in the time domain, the performance will degrade for the case that the separation degree of overlapping chromatographic peaks is low. Aiming at this problem, this paper proposes a method based on quadratic differential and wavelet transform. It is shown from simulation results that the proposed method can effectively deal with the overlapping chromatographic peaks with lower desgrees.
