Portable potentiometric device for determining the antioxidant capacity

نویسندگان

چکیده

At present, the development of portable devices for express assessment content biologically active objects, such as antioxidants, is one relevant technological problems modern chemistry, medicine, and engineering. The main advantages are simplicity rapidity analysis, small volumes analyte, well miniaturization equipment, making it possible to carry out on-site analysis and, thus, take a step towards personalized medicine. potentiometric method using K3[Fe(CN)6]/K4[Fe(CN)6] system, which in laboratory-scale version proved be most accurate, reproducible, express, was basis developed prototypes devices. In this study, two versions device proposed, namely, open microcell with 0.2 ml volume microfluidic flow control. correctness antioxidant capacity (AOC) determination both systems confirmed by comparing results "introduced-found" on model solutions antioxidants their mixtures AOC obtained standard laboratory electrochemical cell. relative deviation did not exceed 10%. some beverage industry determined device. correlation coefficient results, cell, 0.90, indicates good data convergence possibility implemented assess multicomponent objects.
