👉 Electroanalytical refers to a type of analytical technique that uses electrical signals or voltages to measure chemical or biological substances. This is commonly used in fields such as environmental science, medicine, and biochemistry. The measurement process involves applying an electric current through a material, which changes the electrical properties of the substance under investigation, such as conductivity or resistance. These changes can be measured using various techniques, including voltammetry, electrochemical impedance analysis (EIA), and electrochemical sensors. Electro
