This function sets up reasonable integration pa-

rameters in the following way (assumes that

several peaks are marked manually in the peak

editor mode (see section 4.5.4) and wrong

peaks deleted):

Slope

is set to 3.

Asymmetry

is set to 1.5.

Width

and

Broadening

are calculated by fitting

a straight line through the measured peak

halfwidth values vs. retention time.

Width

is

determined as the y value of this line at the

Delay

time,

Broadening

is calculated as the y

value at the end of the chromatogram di-

vided by the y value at the

Delay

time. If this

procedure does not provide adequate result,

Width

is set equal to the minimum value of

peak width for the chromatogram,

Broadening

is set to 1.

Integration parameters

window for definition of integration

events. Integration events have a higher priority than integration pa-

rameters and are used for fine tuning of the integration process. They

should be used only in the case when problems cannot be solved by

tuning a set of parameters from the integration parameters window.
