Update: FID output signal was very low even when trying to ignite, so we checked the interconnect spring and noticed it was shorter than the ones in the other GCs (not that close to the detector base; dont know if it was always like that or something…
Hi,
We are struggling to solve an issue with an Agilent 8860 GC-FID we purchased in 2019. It is used to quantify propane in headspace samples that are manually injected. It is possible but unlikely that some of those headspace samplings result in the…
Tip for other users that may encounter an FID Ignition problem: try blowing on the FID when it is trying to light. If the FID lights - there is an issue with the gas flows. It is best to use a flow meter like the ADM Flow Meter for gas chromatography…

Hey. Johnson we solved the Problem by removing the igniter Castor with collector nut and the spring locks Info the right place. Another Problem could be the malfunction electrometer.
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 …
Hello DET ,
Sorry for the late response on this.
What sort of spiking do you see usually? What is the output of the FID, in pA?
Are you using any UPS systems, or are the GCs plugged directly into the wall?
Hello what9000 ,
I have a couple questions to try to understand this better:
- What is the outlet voltage?
- Is it a dedicated circuit?
- Are you using any UPS systems, or is the system plugged into the wall directly?
