Hi, can you help me, please. I have problem with GC. Is it possible that oxidation of ECD happen due to lack of N make up during the anylisis.

ECD machines staying spare can catch atmospheric O2 and yes, the detector loose sensitivity.
As far I remember Gurus recommend heating it high (up to 350) and conditioning up to 8 hours. If possible - switch from N2 to H2 (to remove oxidation), obviously be careful because in that case H2 is not burned.
