Good morning, everybody!
I am currently doing untargeted analysis using the Unknown analysis software. I could «identify» some compounds of interest, which is great. Now, my next step is to do a semi-quantification of my compounds using my internal…
We have OpenLab 2.1 (with content manger) running our GC and LC systems. We have successfully been running 2 x GC and 6 x LC systems however this morning on two of the systems we can see the following error:
Acquisition
Failed to connect to the…
Hello everybody,
I operate an Agilent 7890B-GC/5977A-MSD and a 7820A-GC-FID, both with autosampler.
Those systems are yearly maintained by Agilent.
So far, GC-MS is for qualitative analysis (compounds identification through library search for…
I looked at your plot again. That little bounce is barely 0.01pA -- so very tiny! This is down in the lowest possible signals that can be measured with an FID and honestly should not matter as your smallest peaks of interest should be at least 50x to…
We run a lot of our GCs with Polyarcs (methanizers) and FID responses can be theoretically calculated. While upgrading the software and importing chemstation methods, the calibration table did not get imported. If I could manually edit the calibration…
Update: I checked filament and looks fine. Weird when switching from EI to CI source the tune fails 3x in a row and then passes every time after that. This happened twice after switching source. The tunes that pass though do not seem like everything is…
Hi Tom, we were told to upgrade to version 10.1 and it solved this issue. However, we found different strange behavior of manual integration. General integrator sometimes fail to integrate peak while manually integrating. What I still don't understand…
Hello, From the screenshot you posted the error that appears to be aborting the method run is "Failed to set injection volume". For a headspace sampler the injection volume should be the sample loop volume which is part of the instrument configuration…
We have experienced this but on a 5975. The cooling fan for the turbo pump failed to restart after maintenance. The error message however did not refer to the fan at all. The easiest way to check if the fan is working is to hold a Kimwipe or other tissue…
