7.4.2 Setup
Tab Setup of Integration parameters window with integration pa-
rameters. The two most important of these parameters for peak
recognition are
Width and Slope .
If the signal-to-noise ratio of the chromatogram is high enough
(e.g. 100:1 or higher), the integration algorithm is not too sensi-
tive to changes in integration parameters. On the contrary, if the
baseline noise is high, careful tuning of these parameters may
be needed.
Number of peaks Number of peaks detected (read-only).
Channel Data acquisition channel for peak detection
(read-only)
Delay Time delay before starting peak detection
(in min).
Entry range:
0 … 1440 min
Width Peak width (at the baseline, in s).
This parameter is used for setting baseline
start and end points. If this value is too low,
excessive narrow peaks are detected from
the baseline noise. If it is too large, several
adjacent peaks or baseline drift can be in-
tegrated as a single peak. For an optimal
evaluation, it is recommended to enter the
