Baseline Correction
Based on the peak recognition algorithm, Chromeleon can calculate a
baseline I-t plot for each data point of a peak. Each I-t plot measured at a
given retention time can be corrected by subtracting the calculated
baseline I-t plot from the 3D amperometry data. By definition, if baseline
correction is enabled, 3D amperometry data is zero unless a peak is
present.
To enable baseline correction, select Baseline correction on the General
tab page of the 3D Amperometry Decoration dialog box.
