Optimizing the detector
AZURA® Detector DAD 6.1L, DAD 2.1L, MWD 2.1L Instructions, V6700
6.7 Subtraction of the baseline chromatogram
The baseline subtraction can eliminate the effects of drift that result from
solvent, gradient, or flow programming. The baseline profile is subtracted
from the measured chromatogram. This results in a mathematically repro-
cessed chromatogram with an ideally flat baseline.
6.7.1 Extended linear range
Upon activating the extended linear range option it is possible to broa-
den the linear range of the AZURA detector, through internal stray light
correc tion. This option can be activated in the used software under
advanced settings. You find further information in the respective software
instruc tions.
The Extended Linear Range option is available for devices with firmware
versions 01.23 (DAD 6.1L) and 01.10 (DAD 2.1L, MWD 2.1L) or higher.
