I have a problem with my residual solvent determination with headspace injection.
I use an agilent G1888 Headspace with Agilent 6890 GC / FID detection
This is how the chromatogramm is supposed to look like

This happens in 1 out of 20 injections
Could somebody help me out?
I already changed both needles of the HS Sampler, the septas, the liner in the GC, and the column.
Should i change the detektor?
