New FID Jet!
The latest FID jet is intended for use in 6890/7890/8890/8860/8850/9000 GC models
The legacy jets will not work in the 8890/8850/8860/9000 GC models
The new jet makes installing the column seamless with a conical shape to direct the…
Hello, I'm new here and having problems with FID Igniting and concentrations of standards and samples are lower than expected.
I'm using GC Agilent 7890B, GC ran out of air on the weekend, we replace the air tank today as usual and since the FID has…
Hello collrube ,
No such thing as a dumb question
Just so I can understand the question better, do you mean that you used to have a 5890 GC FID system, and you replaced that with an 8890 GC FID system? Or do you mean that your FID on the 5890…
Hi all,
I have taked the FID from a HP 6890 plus and put it on a Agilent 6890N that had two inlets and two ECD detectors. I only use the front inlet and installed the FID on the front detector, and removed the electronics for the second inlet and…
I have a 5890 GC running ASTM D2887, simulated distillation. It is equipped with a FID and recently we noticed the FID won't light. Flows are good and gases are good. Looking at the setpoint/actual reading, it states it is at the correct temperature …
Hey guys,
I noticed that my FID Signal (6890N) started fluctuating and deducted that the signal fluctuation corresponds with a fluctuation of the H2 Gas Flow for the FID.
Has anybody had this problem before? Is the FID leaking? Might the PCM Module…
Hello CMZainea
unfortunate this problem still hawe
With the help of the user's manual, we already finded several reasons and troubleshoot the error.
They are:
"Check the FID jet for clogs or damage. If the jet is clogged, you can try cleaning…
Hello Community
We have a reproducabiility problem on GC-FID's. We run an alkane standard every day in the morning. Peak shapes are looks good but when i compare the total area of the peaks over the last weeks an month, its very bad, i have a standard…
Hello SimonHarries ,
The only time I have heard an FID trying to re-light itself is when the baseline of the FID dropped below the Lit Offset value.
What is your baseline at (in pA) when the FID is lit, but not running sample? And what is your lit…
