Hello Samehalsharawy ,
Can you please elaborate on the statement we uninstalled the cylinder expecting the flow to come down to zero but it didn't. It stayed at 50?

I was experiencing ghost peaks in my water blank shots so I decided to do some maintenance. This included a new S/SL liner and septum, removing the first inch or two of the column, FID disassembly and ultrasonic cleaning of the jet, and reassembly. Now…
Hi, thank you for your reply.
I am trying to process metabolomic sample .d files generated from an LCMS-QTOF. I did not get this problem a month ago, however, to solve other problems with permissions I had to uninstall and reinstall profinder.

I have a problem with my FID on a HP-4890d Gas Cromatograph.
The FID was working as normal, then the FID didn't start, so I checked the gas flows, and the H2 didn't come out from FID.
I suspect maybe the Hydrogen pipe line is clogged or the on/off…

Hi all,
We have a 5975 MSD that is failing to pump down. The turbo pump (Pfeiffer HiPace 300) does not appear to be spinning up, though the turbo pump electronic drive unit has power and is displaying LED light activity. The rough pump has been serviced…
A customer has the MP-AES 4200 for soil analysis but recently started to have a problem with the ignition of the plasma or keeping the plasma on. The customer reported that was a problem with the exhaust system or the inlet fan (cooling system). I checked…
BioConfirm was not designed as a proteome search engine. Searching for proteins using intact mass may not work since the proteome databases are based on DNA reads and include signal proteins/peptides removed from the expressed protein and the fasta file…
Why noise? I don't see a problem with noise.
With regards to the failed drift results, officially the test is to be run with a flow rate of 0.5 ml/min.
Hi Guys, I have a 7980B GC with an external injection valve and FID detector. I am using OpenLab CDS Chemstation Version C.01.09 with Windows 10 (version 1703). Sometimes while running a sequence it fails to save the chromatogram. When you select the…
