Replacing Ise Electrodes - Siemens ADVIA 2400 Maintenance Procedures

To prevent infection, by contacting serum directly, wear suitable protective gloves
when you remove the electrode from the solution.
NOTE
High-concentrated salt water is used as a preservation solution to maintain electrode
performance. When the electrode package is opened, wash the electrode with
sufficient water and wipe well before use. Small amounts of salt on the electrode may
cause rust on the electrode connector.
NOTE
Storing the reference electrode:
a. Remove the reference electrode from the ISE module.
b. Rinse the reference electrode with deionized water.
c. Place it into an appropriate container.
d. Cover the reference electrode with reference electrode filling solution.
e. Cover the container and store at -18 to 4.5 °C (0 to 40 °F).
f.
7. Replace the electrodes on the instrument with the newly conditioned ones.
8. Calibration is performed as part of the electrode replacement.
9. If the calibration fails, repeat the calibration.
10. If data continues to be unstable after electrode conditioning, perform an electrode
wash, then perform calibration.
