“An oxidation-reduction system, or redox reaction, involves the transfer of electrons from a reductant to an oxidant according to the following equation”2: (fig. 1)
At equilibrium, the redox potential (E), or oxidation-reduction potential (ORP), is calculated according to the Nernst equation (fig. 2) where R (gas constant), T (temperature in degrees Kelvin), and F (Faraday constant) are constants. E0 is the standard potential of a redox system measured with respect to a hydrogen electrode, which is arbitrarily assigned an E0 of 0 volts, and n is the number of electrons transferred.
The RedoxSYS® System provides both an aggregate measure of redox imbalance (static ORP, which is the tendency of a system to either donate or take up electrons) and an aggregate measure of antioxidant reserves (capacity ORP, which is measured in coulombs or concentration).
