Agilent GC 7890A, FID, Split Liner. I'm setting up the column to do Hexane injection testing. It was set up this way previously but the program had been deleted and the column removed before I started here. Front Detector/Column which is below baseline…
I'm going to be calibrating for ethanol on my HS-GC-FID 6890, but I'm having discrepancies between two standards. The standard that I will be calibrating with (Restek's Residual Solvents #1 34105) is 3000ug/mL in N,N-Dimethylacetamide. I'm verifying the…
Hello from Kazakhstan,
Very interesting theme.
I also have some issues with flow method correction and some questions.
1) We use Excel CFT calculator. So how much pressure we should put on calculator, when using SCD detector with FID? As calculator…
What you describe with the washes happening, but a delay when pulling up the actual sample for injection sounds like something about the GC is not in a ready state and the GC is waiting for a part of the GC to become ready. In this case you describe it…
Thank you for your advice. Unfortunally not only EM test failed but several others as well. we tried to run it last,first, and even not to run it at all
Hydrogen (H2) is the simplest and most abundant element in the universe. Since, it only occurs naturally on Earth when combined with other elements it must be produced from other sources. It can be produced without a carbon footprint from variety of sources…
Yes, the MassHunter software uses a conversion factor and reports in "counts" instead of hertz for uECD data. The conversion factor is 7680.
The 7680 multiplier also applies to other GC based detectors such as FIDs and TCDs.
Hi,
We are using MassHunter 10.0.368 to collect data on a GC-FID (7890B). The software will randomly crash (the software shuts down with no information in the logbook) during a sequence, usually after 100+ samples. We have updated MassHunter to version…
When you say that there are no signs of a leak, have you run a pump leak rate test using Agilent Lab Advisor? If not, I would suggest testing this. If you're unlucky enough for your peak to elute just at the point when the outlet ball valve fails to close…
Hi
I am pretty new to GCMS, so may need extra details on how to do things you suggest
I attached a picture of the set up of our gc system, so I can explain better. We recently installed a guard column using 30 cm piece of FS Deactivated 0.250 mm(Agilent…
