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…
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.
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…

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…
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…
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...

Hello,
I previously had Quant 11 on my personal computer and decided to upgrade to Quant 12.1. When I tried to use the installer I get an error that "Set up was Interrupted" and fails to install. I tried to go back to Quant 11 but now get the error…
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…
