For the baseline correction, the application evaluates the following spectra:
Spectrum at the baseline start of the peak
Spectrum at the baseline end of the peak
Baseline start and end times depend on the integration. If multiple peaks are only separated by a drop line, all peaks use the same spectra for background correction (see Baseline start and end depending on integration).
A linear interpolation of the two baseline spectra is calculated. To correct each individual peak spectrum, the application subtracts the interpolation spectrum at the corresponding retention time.
