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…

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…
Hi everyone, My MP-AES 4210 Machine sa is failing to suck/take-up the samples from the sample tubes..
I tried changing the sample pipes but nothing worked. Kindly asking for help on how to sort out this problem?

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…
