Dear team,
We have an G4212B DAD detector. We have an issue with baseline. Please see below. It's water 1 ml/min. 254 nm (4mm), reference 500 (100mm)
below results flow off, Max light Cell 10 mm.
below results flow off, Max light Cell 60 mm.
We flushed the flowpath for two days: IPA, MeOH and water. We have tried with column and with zero dead volume fitting.
What could be the possible source of such drift and noise in baseline?
Thank you all in advance.
Kind regards,
Rustam
