Hi all,

I have for the first time polished our ECD measuring cell and just cleaned it afterwards by wiping it with acetone and water. Now I registered a drift in my measured data and a much higher Icell value. Is it necessary to passivate the cell after the polishing when using a 96% citrate 4% acetonitrile mobile phase pH 4.3? Or would it be useful to autozero the system? Do you have some recommedations for me?

Thanks in advance :) any kind of advice is appreciated
