Broadening Broadening for peaks in the end of the chroma-
togram compared to peaks in the beginning.
This parameter is used for automatic adjust-
ment 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 algorithm) 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 tan-
gent skimming. This function is switched off al-
ways 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 setting is rec-
ommended for very sensitive determinations
with high noise
