Margin For Negative Absorbance Settings; Optimizing The Detector - Agilent Technologies 1100 Series User Manual

4 Using the Detector

Margin for Negative Absorbance Settings

1 To change the settings select Setup Detector Signals.
2 In the section Margin for Negative Absorbance change the value according
Figure 50
The higher the value the greater the baseline noise. Set this value only if you expect
N O T E
negative absorbance greater than -100 mAU.

to your needs.
Use this field to modify the detector's signal handling to increase
the margin for negative absorbance. Use this option if, for
example, your solvent gradient produces a decreasing baseline
absorbance, and for GPC analyses.
Limits: 100 to 4000 mAU.
