Hi Agilent,
Due to helium shortage, we need to change carrier gas for our GC-FID. Most documentation for Agilent suggests either H2 or N2, and the Chemstation configuration shows those options as well.
We are considering using argon, however, I…
Carbon disulfide is another option for wash solvent when running naphtha or crude oil samples. It's response on FID is low compared to hydrocarbons, so there should be little to no response if some residual is in the syringe.
Since the FID and TCD are in series, I would guess that the extra noise on the peak through the FID is due to the TCD valve switching between carrier and reference. Try setting the FID signal rate to 5 Hz. Also, the FID makeup flow can be reduced or turned…
There's a lot going on. You have Column 1 in Constant Flow to a PSD in Constant Pressure with PSD Purge at 0 ml/min. Is there a purged splitter plate installed or a Purged Ultimate Union? The flow into the MS changes throughout the run due to the PSD…

This problem occurred after updating Openlab CDS Software 2.2 Version to 2.4 Version. GC# 7890B With FID , and TCD Detectors With OpenLab CDS Software 2.4 After installing the software version 2.4 and after a gas sample injection I noticed that there…
Dear Colleagues,
I have GC-FID 8890 and i'm using Gas saver feature but I'm observing when I change time of gas saver , the retention time is changed.
for instance, I set gas saver at 20 ml/min after 2 min then inject methanol and the RT is 4.74 but…
The boxes of standards should have shipped with a Certificate of Analysis enclosed. If you go to Agilent.com, you can search on the part number. A number of the hits are CofAs from different batches. part 5080-8858 CofA Lot CF-4631W.pdf (agilent.com)…
Ah, and I think the issue has to do with that I have 2 autosamplers, and 3 columns (MS at back, and 2 different FID columns at front using a 2way splitter). So the MS signal is in the subsequent folder, the FID1 signal is in the correct folder, and FID2…
Hello,
To calculate the RSD and Pass/Fail results, one can try the following:
In the reporting go to the edtor and open "table properties"
In my specific case, I want to calculate RSD for Area, so I choose the column A, pA*s and press "Column…
