DOXの原理

Principle of counting bacteria: What is the

 

Since oxygen is dissolved in the culture medium, the following chemical reaction will occur in DOX cell cartridge equipped with electrodes:

O2+4H++4e- = 2H2O


This reaction generates a small amount of electric current at the electrodes.  By measuring a change in the amount of current, the change in the dissolved oxygen concentration will be known.
