Abstract The invention provides a correction method for detecting hazardous substance residues by using ion mobility spectrometry. The method comprises the following steps: establishing a standard ion mobilityspectrometry database of a substance to be detected, and setting an alarm threshold value; taking a to-be-detected sample and carrying out ion mobility spectrometry signal acquisition, repeatedly carrying out ion mobility spectrometry analysis on the same sample when an instrument issues an alarm, respectively marking measurement results of two times as a first ion mobility spectrometry signal and a second ion mobility spectrometry signal, comparing the second ion mobility spectrometry signal with the alarm threshold value, comparing the second ion mobility spectrometry signal with the firstion mobility spectrometry signal when the second ion mobility spectrometry signal exceeds the alarm threshold value, if the intensity of the first ion mobility spectrometry signal is greater than or equal to 20%, automatically
