AI Technical Summary
In existing technologies, impedance changes caused by electrode aging are difficult to distinguish from decreases in reactive oxygen species concentration, leading to inaccurate control of reactive oxygen species concentration and affecting the reliability and accuracy of test results.
By dividing the cutoff frequency in the electrochemical impedance spectroscopy data into frequency ranges for reactive oxygen mass transfer and diffusion processes and electrode interface charge transfer processes, the concentration characteristic region and electrode characteristic region can be distinguished using the cutoff frequency. Combined with the control of pumps and solenoid valves, the concentration of reactive oxygen can be precisely regulated.
It effectively avoids the impact of impedance changes caused by electrode aging on the control of reactive oxygen species concentration, ensuring the stability and accuracy of reactive oxygen species concentration in long-term testing, improving dynamic response speed and control precision, and ensuring the stability of the testing environment.
