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
