Hi Lance.
Setting the FID to 5 Hz fixed the peak noise issue. I did notice however that when lowering the makeup flow on the FID < 5 ml/min (set it at 3 ml/min) there was loss of sensitivity in the FID. I set it back to 25 ml/min and the sensitivity…
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)…
Thanks for the comments I have pasted the requested information below:
This is a new one for us as our lab has been running these instruments for 20+ years and can't ever remember this as a problem. We run trace level organics and almost always splitless…
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…
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?

Hello!
It would be very good to get step by step instruction and definition of each row on Splitter calculator and other calculators to configure our system.
The system uses SCD and FID detectors.
Target is to get ratio 3:1 between SCD and FID for…
