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.
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…
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…
Hello experts!! I have 6460 LCMSMS system. It unfortunately failed in tuning even in brand new tuning solution. Auto tune repeatedly failed in peak width adjustment in MS1. What could be the problems and possible answers? Cleaning is done up to ion transfer…
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…
I'm trying to create a report with a column which calculates the percentage of all integrated peaks above a specific threshold. I have created a report parameter to format the number of significant digits, this is a request of some of our clients. At…
I found the issue. I have "Hide duplicates" selected which prevents any additional Fails from being displayed. However, if I uncheck that box, there is a Fail in every row. This is a summary result, is there a way to make it display only once per group…
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…
