Abstract

A portable device and a method for the measurement of antioxidant capacity in liquid samples based on electrochemistry, specifically in voltammetry. The device applies a range of potentials to a sample and receives the current signal that is converted by a mathematical method into a total value of the antioxidant capacity represented on a scale of 1 to 10, indicating the value of the antioxidant capacity. highest and 1 the lowest. This method considers three oxidation regions of antioxidants for which the load value is calculated, called Q1Q2and Q3 . In this way, differences can be observed in the antioxidant capacities of two samples whose total load was equivalent, but nevertheless, present different values in the three established regions, being more accurate and faithful to the operation of the ROS purification systems.
