Margin for Negative Absorbance (Integrated LC DAD)

Margin for Negative Absorbance

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.

The higher the value the greater the baseline noise. Set this value only if you expect negative absorbances greater than -100 mAU.
