9.24.2 Replacing an Amperometry Cell Gasket
These instructions are for conventional (nondisposable) working
electrodes only. To install a disposable working electrode, refer to the
manual, which is shipped with the electrode.
When to Replace the Gasket
Replace the gasket if there is a leak between the gasket and electrode, or
between the gasket and cell body.
Items Needed
• Amperometry cell gasket for nondisposable working electrodes
(P/N 045972)
• Gloves
• Blunt-end tweezers
Amperometry Cell Gasket Replacement Procedure
NOTE To avoid electrode fouling, always wear gloves when
handling electrodes.
1. Turn off the cell voltage from the Control panel in Chromeleon or
Chromeleon Xpress.
2. Turn off the pump flow from the Control panel in Chromeleon or
Chromeleon Xpress or press
PUMP FLOW on the front of the pump.
3. Disconnect the cell (see Section 9.24.1
).
4. Loosen the PEEK yoke knob holding the working electrode to the cell
body by unscrewing it two to three turns.
5. Squeeze the tabs on the sides of the yoke block and pull the block and
knob off the working electrode (see Figure 9-33
).
