Margin For Negative Absorbance Settings; Optimizing The Detector - Agilent Technologies 1260 User Manual

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 49 Margin for Negative Absorbance
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.

on page 115.
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.
