Level refers to the magnitude of the signal.
•
Slope refers to the value of the signal slope of the signal.
•
Level and slope triggers fractionation when both the
magnitude and the slope reach the specified value.
•
Level or slope triggers fractionation when either the mag-
nitude or the slope reach the specified value.
Set the threshold value for detection of peak start. The peak
start is detected when the signal exceeds the specified value.
Start level/
Start slope
Set the threshold values for detection of peak end. The peak
end is detected when the signal falls below the specified value.
Note:
The value for End slope is implicitly negative. The minus sign is
not shown. The peak end is detected when the slope value is
negative and rises arithmetically above the specified value.

Enter the minimum peak width value in minutes. Peak end will
not apply until the peak has reached the minimum width.
