Cleaning The Electrodes - Agilent Technologies 7100 User Manual

Cleaning the Electrodes

1 Flush the electrodes with water. Watch for salt crystals. All salt crystals
Figure 64
2 Flush the electrodes with isopropanol.
3 Use compressed air to dry the electrodes and remove all traces of liquid.
Increased leakage current and arcing due to wet electrodes
C A U T I O N
Increased leakage current and arcing might appear during analysis if electrodes are not
completely dry.
• To avoid contamination, the inside of the electrodes must be completely dry before
If there is still an accumulation of dirt in the upper funnel or inside the electrode start the
N O T E
cleaning procedure again. You may place it in a beaker of water or isopropanol and treat this
in an ultrasonic bath for 5 minutes followed by steps 2 and 3 in this section. If this fails,
replace the electrode.
