-Have you tried a diferent column ? An old column could have retention time issues and peak distortion.. -Have you had any pressure fluctuations during your run ? Try running a Pump leak rate test, to see if the problem is not in the pump-head. -Do a…
On a G1329B autosampler I lose the plastic housing to have access to a valve. Then I forgot to reassemble it and when turn the unit on, the needle went to the top.
Now, I cannot put the plastic housing back, and interferes with the arm.
I…
Hi BJohnson would you post your question in the Chromatography Software Forum for better visibility? It would be good to provide the system information (hardware details, software, i.e. OpenLab CDS and software version).
Cheers,
Kristen
