Hello, H2 is the fuel for the flame in the FID, so if you are out of H2 then the FID will not be able to light. That is very likely the reason why you are not seeing a signal from the FID.
I have a 6490 QQQ. Each time I run either autotune or check tune, I get masses that are out of tolerance especially in MS2. The system seems to pass if the Dynamic Ramp Table enable button is checked. This is associated with the collision cell and detector…
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was?
From what I understand…
Based on your latest results, I would say that nothing is fundamentally wrong with the optical unit in terms of noise, so I believe this is more an applicational problem - your passed quick noise test points to that direction. The error 1050 with the…
No, the flows on the two columns downstream of the switch have to be equal. They are feed by the same pressure source, so since MSD is under vacuum and the FID is ambient, the column connected to the MSD has to have more restriction, to keep the flows…
I have decades of experience with consumer products, all on Agilent GC, GCMS, and HPLC.
If I was needing to quantitate 1,2-octanediol in cosmetics samples, I'd extract the sample with dimethylformamide and add BSTFA to make trimethylsilyl derivative…
Disconnect the sample probe from the valve and start the leak and restriction test. If it passes this step, it means that there is some restriction in the sample probe, enough to cause that part of the test to fail. Try a brand new probe. If it fails…
Seems then to indicate something in the flow path when including the mixer and damper. First, make sure that you do an elasticity calibration because you have changed important parts in the flow path. Then re-run the pump leak rate test with the mixer…
Hello everyone,
We have a problem with the acquisition methods on GC, but not on HPLC.
When we want to change an acquisition method that is in "approved" status to "generic" status in order to modify it, it is impossible to do so because the box is…
