1. Loosen the outlet screw and insert a syringe. It’s
easier if the outlet tubing is disconnected. Suck
the liquid from inside the ECD cell. Without this
step, the gasket will become wet by the mobile
phase when the cell is disassembled, resulting in
some problems.
2. Pull the handle slowly and then draw the shaft out. The cell
is now open.
3. Lift and remove the setting plate, working
electrode and gasket in turn.
4. Carefully wipe the surface of the electrode
(smoother side) with acetone using a Kimwipe.
Always wipe in the same direction. Do not rub it
back and forth. Please be extremely careful not
to damage the surface.
In this photo, the ECD cell is disconnected from
the ECD but it’s not necessary for normal use
