👉 Electroanalysis is a scientific method of analyzing materials by using electrical signals to measure their chemical composition. It was first introduced in the 19th century and has since become an important technique for studying metal, nonmetal, organic, inorganic, and complex materials. Electroanalysis involves the use of voltages and currents to identify the presence and concentration of various elements or compounds in a material. This method is widely used in industries such as electronics, pharmaceuticals, and environmental science.
