Hi Guys,
I have a GC that does not seperate natural gas(maily C1 and C2 with small traces of C3+), it comes as almost one peak, and for condensate (C3+) it seperates C6+, and does not seperate C3÷C5,
I Have,
1: Readjusted the split ratio Many Many…
hello everybody
Who Can help me ?

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…

I am using Agilent 8890. I am trying to set the standard for my GC-FID, I am injecting 5mL of methane gas standard with a gas-tight syringe through a switching valve which is set up to the left of my GC. However, I am getting different peaks and areas…
Dear All,
We are using NGA analyser as per GPA 2286 method using FID and TCD.
Could you please advice how to apply the bridging to correct the concentration from FID.
We have a GC-MA7890B with an FID detector and I are observing spikes in the baseline after we made a couple of changes.
We installed guard columns with unions on inlet and detector side, added a 2nd gas cylinder and required tubing, cleaned the FID…
