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…
Good morning It turns out that this is the first time something so particular has happened to me with my GC-MSD (6850-5975). I work with MassHunter 10.0.368 and from one moment to another the signal for two of my work standards (organophosphates and phenols…
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 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…
Hello jeremy_lai ,
In your expressions you must check for both the existence of the qualifier and the outlier yourself. In the initial if and in the final one you need to add a check to see if there is a qualifier by checking to see if it is None. …
