Preparation of Carbon Paste Electrode
Carbon Paste Oil (CPO) is prepared by mixing uniform-sized
graphite powder and paraffin oil.
1) To fabricate simple enzyme electrodes
2) To fabricate chemically modified electrodes
Instruction manual for preparing Carbon Paste Electrode
Packing CPO into a carbon paste electrode well
 |
Used CPO in the electrode well is removed from the well using a small rod such as toothpick |
 |
A new CPO is filled to the electrode well with a small spatula |
 |
CPO is completely tamped into the electrode well filling air spaces, and slightly heaped up above the surface of the well |
 |
The excess CPO above the well is removed on a clean and at paper as shown in the left figure |
 |
The surface of the electrode is moved to a clean area of the paper, and is polished using circular movement on the paper |
