A new method for reconstruction of chromatography signals with drift of base line and noise contaminated is presented.The baseline correction method is developed based on discrete drift points detection
and the noise on base line is depressed by using wavelet transformation method to great degree.This method is suitable for both online and offline processing of chromatography signals.It is used in portable GC with SnO2 sensor as detector.The baseline correction and noise restraint of chromatogram in TVOC analysis are realized.The satisfaction results are achieved.
