Hello, I have initialization problems with my software, MassHunter Workstation software, LC/MS Data Acquisition for 6400 series triple quadrupole Version B.08.00, a service engineer from the brand representative recommended that I uninstall the software…
Dear Community
We faced problems with our GC 7890B which is connected to a Leco Pegasus BT. Since this week we have a really high noise, which comes regularly every 5seconds. We already cleaned FID many times, replaced Jet and built the FID out an in…
Did you finally determine the cause of the inconsistent results? I'm having a similar issue with a different instrument. I have gone through my troubleshooting list and failed to identify the issue.
Hello
We are working on developing a method for detecting mineral oil contamination (MOSH and MOAH) in edible oils. We are able to get MOSH (mineral oil saturated hydrocarbons) to work well, but when we inject a sample for MOAH (mineral oil aromatic…

I think our only problem at the moment is a hardware issue (EPC failing to shut makeup gas OFF when called for) that prevents FID ignition… we’re putting in a call for service to resolve that. I’ll be working to resolve user error (Comments Edited by…
Hello,
Are you sure the end tip of the PLOT column ends up (and 2 mm withdrawn) inside the FID Jet?
Any problems when igniting the FID?
FID Jet could be contaminated from PLOT stationary phase particles ..

There are two log files. The main file looks like a lot was going on.
I went back and did a search for "error" and found the following:
Could not create system restore point, error: 0x80070422. Continuing...
Error 0x80096010: Failed authenticode…
No I haven't. But I think that is the only solution. Perhaps there are somehow misalignment making it not robust and the needle fail to go in the vial and abort the run randomly. . I will do the auto-reference and I will wait and see how frequent the…
