How does the e-BQC measure?
It oxidizes the sample by applying a variable potential. A variable voltage is applied to the strip to “activate” the antioxidants, so they cede the electrons. Electrons are released and detected as a current at the electrode.
What do the results mean?
The results are given as the total charge (uC) of the electrons that are able to be donated to a free radical to neutralize it in the sample.
Traditional methods of TAC measurement are laboratory tests. These are based on the generation of a free radical type and the ability of the molecules present in the sample to eliminate these radicals. These assays are hardly comparable among them.
