Elektroanalyyttisessä

Elektroanalyyttisessä refers to a field within analytical chemistry that uses electrochemical methods to determine the presence and quantity of substances. It involves measuring electrical properties like current, voltage, or resistance as they relate to a chemical reaction occurring in an electrolytic cell. These measurements provide quantitative information about the analyte.

Several techniques fall under the umbrella of elektroanalyyttisessä. Voltammetry, for example, measures the current that flows through an electrochemical cell as the potential is systematically varied. Coulometry involves measuring the total amount of electrical charge passed during an electrochemical reaction, which is directly proportional to the amount of substance reacted according to Faraday's laws. Potentiometry measures the electrical potential difference between two electrodes in a solution, which can be related to the concentration of specific ions.

Elektroanalyyttisessä methods are valued for their sensitivity, selectivity, and relatively low cost. They find applications in various fields, including environmental monitoring for pollutants, pharmaceutical analysis for drug purity, clinical diagnostics for blood glucose levels, and industrial process control. The development of sophisticated instrumentation and electrode materials continues to expand the capabilities and applications of elektroanalyyttisessä techniques.
