Good morning,
We have an Agilent 7820A GC-FID equipped with a G4567A autosampler.
In the middle of a sequence, the system gave the following errors:
ALS Failure State: Preparing Samples
ALS Failure Code 945 : Autoinjector back tower plunger…
Hi All, I'm trying to get the following expression to work in a Qual 10 report (in excel format as that's about the extent of my coding knowledge): =IF(Area<DB_Notes,"Fail","Pass") to flag compounds which are less than a defined minimum peak area (which…
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…
Are there electronic checks that can check to make sure a filament isn't failing because of an electronic issue? We had a filament die, which isn't too surprising considering it was nearly ten years old (teaching institution, the instrument sees periodic…
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…
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…
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…
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,
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…
