The invention relates to a chromatographic instrument which comprises a sample inlet, a chromatographic column, a detector and a signal processing module, and the signal processing module is used for processing an electric signal detected by the detector to obtain a chromatogram; the signal decomposition and filtering module is used for performing empirical mode decomposition on the chromatographic signal of the chromatogram of the target sample to be detected to obtain an eigenmode function and a high-frequency signal of the target sample to be detected, and performing Bayesian wavelet filtering on the high-frequency signal to obtain a signal after wavelet reconstruction; the empirical mode decomposition module is also used for performing empirical mode decomposition on the chromatographic signal of the chromatogram of the standard sample to obtain a standard intrinsic fundamental mode function; the eigenmode function fitting module is also used for fitting the eigenmode function of the target sample to be m
