Processing tab:
On this tab you can configure
o
the peak detect threshold
o
the minimum peak width
o
the calibration file to use.
Definition of the peak detection threshold:
The Initial peak detection threshold
tells the peak-detection algorithm how
much noise may be expected in the chromatogram. This number is
dimensionless. Appropriate values range from -6 to +28:
•
If the value
is too large, then peaks will be treated as noise, and missed.
•
If the value is too small, then noise will be treated as peaks, and the
chromatogram will be littered with false peaks.
How to determine the threshold:
1. Select
context menu
measure noise
in a real time plot or a loaded chromatogram.
The program will tell you the noise and the recommended threshold.
