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

Rear 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

for linear base-

lines should be selected for asymmetric or double peaks.
