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 work in a small, environmental lab. We test aluminum levels in serum using ICP-MS. We can run batches of 250 samples at a time. We dilute 500 microliters of serum to 5 ml using 0.2% HNO3. We calibrate using 1, 5, 10, and 20 ppb Aluminum std. At the…
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…
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,
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…
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…
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:

Failed to connect to the…
It looks like theres a problem with the back inlet/back autosampler - the gc does not recognize it anymore - but it seems to be defined within the method, meaning it has a inlet temperature ect.
Did you change something regarding the back inlet? or…
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…
