Decreasing sensitivity .
Contamination of the anode surface (e .g .
by sulfide) .
Switch the polarization to -1000 mV for
30 seconds . After this period, switch the
polarization back to +1000 mV . Repeat
calibration procedures when the signal is
stable again .
High and drifting signal .
The sensor tip is broken .
Replace the hydrogen microsensor .
The signal is very low .
Loss of the platinum tip due to excessive
vibrations .
Replace the hydrogen microsensor .
Slow response .
Insoluble compounds deposited at the
sensor tip .
Rinse with 96 % ethanol, rinse with 0 .01 M
HCl and rinse with water .
