Thats my problem.
During the sequence suddenly the signal in uECD increase.
Sometimes one injection is on 300 Hz and next incjection running in 500 Hz.
Sometimes the signal suddenly increase from 300 to 500 Hz during the one incection/analysis.
Its shows in attached chromatograms.

I replace: ferrule from the detector side, ferrule from the injector side, column, liner, septa, traps on hel and nitrogen.
Where is the problem? Does anyone have an idea what is going on?
My GC: Agilent 6890N
Thank you for any help, tips.
