Abstract: A novel overlapping peaks diagram oriented analytical algorithm, named fractal resolving method(FRM), which is based on the fractal theory, is proposed to process analytical signal from instrument. By calculating the fractal dimension of the signal, which can effectively reflect the characteristic of each signal, the information of the peak numbers and peak positions can be accurately obtained. The method will avoid the error generated by man-made estimate and fulfilling the separation of the overlapping peak signals. The experiment results showed that FRM was a powerful tool for processing the peaks signal.

Key words: Fractal resolving method, Overlapping peaks signal, Fractal dimension
