Elektroanalytiikan

Elektroanalytiikka, also known as electroanalytical chemistry, is a branch of analytical chemistry that uses electrical methods to study and quantify chemical processes. It encompasses a variety of techniques that involve the measurement of electrical signals generated by chemical reactions at the interface between an electrode and an electrolyte solution. These techniques are widely used in research, industry, and environmental monitoring due to their sensitivity, selectivity, and ability to provide real-time data.

One of the most common electroanalytical techniques is potentiometry, which measures the potential difference between two electrodes in a solution. This method is used to determine the concentration of ions in a solution, such as hydrogen ions in acid-base titrations. Another important technique is voltammetry, which involves applying a voltage to an electrode and measuring the resulting current. Cyclic voltammetry, a type of voltammetry, is particularly useful for studying the redox properties of compounds and for characterizing electrochemical reactions.

Electroanalytical methods are also employed in the field of electrochemistry, where they are used to study the behavior of electrons in chemical reactions. This includes the study of electrode processes, such as electron transfer and ion transfer, and the development of new electrochemical sensors and devices. For example, electrochemical sensors are used in medical diagnostics, environmental monitoring, and industrial process control to detect and quantify specific analytes.

In summary, elektroanalytiikka is a versatile and powerful tool in analytical chemistry, offering a range of techniques for studying and quantifying chemical processes. Its applications span across various fields, including research, industry, and environmental monitoring, making it an essential discipline in modern chemistry.
