As the title says I see a weird pattern in my baseline, please see attached image: .
I tried uninstalling and reinstalling my column multiple times, but only once did i get a good baseline and THF peak, see next image:
My other attempts at reinstalling still gave me this weird pattern. I tried different liners but to no avail. So my conclusion is that there must be something wrong with the EFC. It is splitless all the way through, could it be that it puts too much strain on the GC (varian 3800)? It seems as if it can't hold the pressure constant when 1 ul liquid is injected (tried with air as well where this pattern is missing). This has only happened in one analysis so far, I have no problem with other analysis. I guess my problem is that I don't understand what is wrong, do you have any idea what might be causing this?
I appreciate your help
