width of the narrowest peak on the chroma-
togram (normally 2
… 10 s).
Entry range: 0.1 … 480 s
Broadening Broadening for peaks in the end of the
chromatogram compared to peaks in the
beginning. This parameter is used for
automatic adjustment of
Width .
Entry range: 0.1 … 100
Slope Threshold for peak recognition.
The value of the first derivation (slope) of
the curve is divided by the baseline noise
(which is estimated using a special algo-
rithm) and the result is compared with the
Slope threshold value. Reasonable range of
Slope parameter is 0.5...5.
Entry range: 0.1 … 400
Asymmetry Ratio of slope threshold at the start of the
peak to slope threshold at the end of the
peak. This parameter is used for automatic
adjustment of
Slope .
Entry range: 0.2 … 5
Min area Minimum area of peaks to be detected.
Min height Minimum height of peaks to be detected.
Rider ratio Ratio of peak heights for two adjacent
peaks. If this threshold value is exceeded,
the smaller peak is separated from the
higher one by tangent skimming. This func-
tion is switched off always if 0 is entered.
Entry range:
0 … 100
Negative peaks If this option is enabled, negative peaks are
also detected.
Interpolate baseline start/stop
If this option is enabled, the baseline start
and stop points are interpolated. This set-
ting is recommended for very sensitive de-
terminations with high noise
