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…
Hello,
For awhile now, I've been having issues with my resolution axis "passing" for masses 25 and 26 in no gas mode. I have done many cleanings and new tuning solutions. Can anyone explain what is causing this continual failing and what I could do…
Hello Agilent community,
I have recently been 'Recovery Test in GMP' of Openlab 3.4 (Build 3.4.0.242) in a standalone environment using the Windows Hyper-V feature.
During the testing, I found the following two issues
First, a warning message…
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 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…
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…
Hello, Just to add on to dnprulz 's reply, the expression that he provided will work in OpenLab Custom Calculator and should perform what you are looking to do. However, if you want the pass/fail logic to be set on the report template then you will want…
After a failed methamphetamine quantitation, it was noticed that the methamphetamine peak shape on our GC/FID instruments has been consistently poor or deteriorating through out a run. This has been happening on both of our GC/FID instruments (all 3 columns…
