Report Variable (Detection Parameters)

Type:

Floating point number

Dimension:

Seconds [s]

Value Range:

0.01 ... 100,000.00

Default:

0.05

Related Parameters:

This parameter should always be considered in combination with the Sensitivity!

Description:

The Peak Slice detection parameter determines the width (= time span) from which several successive data points are interpreted as peak or as noise. The presetting is 5/100 seconds.

Function:

General Rule

If a specific peak should "just" be interpreted as a peak and if this was not reached via the Auto setting, a manual peak slice value can be specified by selecting the peak width.

 Note:

This parameter only refers directly to peak detection and indirectly to integration. For area calculation, the original signal is used. (The parameter influences peak start and peak end. In this way, the peak area is influenced, also.)

To change the variables, Sensitivity and Peak Slice, is only necessary in case of chromatograms comprising very wide (many minutes) or very narrow (< 0.1 s) peaks. Under normal conditions, the default values should not be changed.

Graphical definition is recommended above all for Sensitivity and Peak Slice. For more information see  Modifying the Peak Recognition Algorithm.
