Probable Instrument Fault…
Currently everything is pointing at an instrument issue.
If it’s been more than a year since the last service then this is the most appropriate course of action – call our service desk who will be happy to help you out.
If a service has been recently performed then it’s time to track down where the fault may have occurred.
From the chromatograms and instrument display, are any of the following apparent?
Poor area reproducibility
Unstable retention times
Poor sensitivity
Noisy or unstable baseline
High Back pressure
Low Back Pressure
If not, call our service desk, who will be able to help, on 01227 265333.
