The probability of water precipitation is very low if the FID temperatures are high enough, but in times of 5890 the FID could not ignite well when water was present. In principle a FID can be operated without makeup gas, which manufacturers officially…
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…
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?
If no physical tank is connected to the GC, the GC gas connections are capped…
Hi Marty,
We have a FID and an MS connected to the same system. We only want to acquire the signal of FID, but if we want to report the method parameters we are “forced” to acquire both (we do not really know why and we have already ask the question…
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…

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…

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.
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…
