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.
Many GC and GCMS installs do not have the items needed to complete the installation. GC and GCMS system installs rely heavily on site readiness and customers having all the material needed, like copper tubing, Swagelok® fittings, and regulators. This…

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…
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:

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…
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…
We tried all the above steps, but the problem continued. We had to change the parameters in the Methods file as suggested in another reply from Cendy D. to make the instrument continue
