6. Wipe the cell body with clean, wet and fiber-free soft cloth;
7. Install new gasket, carefully check whether the gasket is flat and fit with PEEK cell body,
and ensure that the two flow passage holes are symmetrically positioned in the center of the
flow channel. Make sure that the gasket is free of wrinkles and bubbles;
8. Reinstall the working electrode fixing block and tighten the knob.
9. Reset the amperometric detection cell and connect cables and pipelines;
10. Turn on the pump and switch on the amperometric detection cell power supply after the
pressure is stable.

To avoid polluting the electrodes, dust-free gloves should be used for operation.
6.7 Replacement Reference Electrode
The time limit of the reference electrode is about three months. The reference electrode
should be soaked in saturated potassium chloride solution when not in use. When the noise is
high or the response sensitivity is still low after polishing the working electrode, the reference
electrode may be replaced.
The operation steps are as follows:
1. Stop the instrument and dismantle the amperometric detection cell;
2. Loosen and remove the reference electrode;
3. Remove the protective cap of the new reference electrode (keep it well);
4. Flush the new reference electrode with ultrapure water;
5. Open the inlet and outlet joint of the amperometric detection cell and install the new
reference electrode.
6.8 Replacement of the suppressor
New suppressors or suppressors that have not been used for a long time (more than one
week) should be activated first.
