- Agilent G1365A produces the error message "Data invalid. At least for some diodes of the array the data produced are invalid due to too much light at a diode or a gain setting."
- Empower 3
The margin for negative absorbance is set too low.
FIX or WORKAROUND
- Change the parameter "Margin for negative absorbance" to a higher value.
It is possible that negative absorbance is high at the beginning of the run, or it may be just a reference issue.
The reference spectra may need to be gathered from another part (a quieter part) of the chromatogram.
One case required an increase in value to 500 mAU.
