Electrode treatment and maintenance

The surface of glassy carbon is easily polluted by some organic metal compounds, which seriously affects the measurement (no peak, no miscellaneous peak, no recurrence), it must be cleaned before measurement.

There are three main methods, one is by chemical method: Nitric acid soaking and scrubbing. The second method is Ammonia water anhydrous ethanol or ethyl acetate (1:1) soak and scrub. The third method is using alcohol after scrubbing and then with 6NHCl or 4NHO3 Soak.

Electrochemical treatment:  i.e.+0.8V-(-1.8V (0.5MKcLPH7exceptO2IRepeated Polarization (Reset) in Voltage Range-Scanning (Anode)-If the cathode is seriously polluted and pitted, scratches can be treated mechanically. MgO Powder (200 Put it on wet velvet cloth and polish it with a little water. Also Several methods are combined according to the condition of electrodes. It is not advisable to immerse the electrode in strong acid, alkali, and organic solvents for a long time.
