An apparatus and a method of chemical analysis entail acquiring a chromatogram, median filtering the chromatogram to produce a model baseline, smoothing the model baseline to reduce noise, and subtracting the smoothed model baseline from the acquired chromatogram to produce a modified chromatogram having a substantially flat baseline.
