CALIBRATION (WITH MICHAELIS SOLUTION):

Composition of the solution : KCl
ATTENTION : do not acidify.
Electrochemical couple involved: [F
The oxidation-reduction potential Eh of a solution is equal to the potential read (E
read) plus the potential of the reference electrode (E ref).
For a reference electrode (Ag, AgCl, KCl 1 mol.L
E ref = 236 mV at 25°C
For the Michaelis reference solution
Eh = 382 mV
Therefore E read = 382 – 236 = 146 mV.
Immerse the mV electrode in the Michaelis solution.
