Baseline calculation
Recognized peaks are evaluated using approximated baselines.
The calculation of a baseline for a smoothed substance peak is
determined by the baseline parameters set for this substance in
the
BASELINE
window (see section 5.2). The following possibilities
exist for baseline calculation:
Linear
Front end
Linear
Rear end
Linear
Whole curve
Start

Polynomial
Whole curve

Exponential
Whole curve

End
As default, the start and end base points of the baselines are cal-
culated automatically. They can be set to fixed voltage values if
desired. The baseline scope
Front end
or
Rear end
for linear base-
lines should be selected for asymmetric or double peaks.
