elektroanalüütilised

elektroanalüütilised refers to analytical methods that utilize electrochemical principles for the determination of substances. These techniques measure physical and chemical properties of a system by observing its electrical response to an applied potential or current. The fundamental basis of electroanalytical chemistry lies in the relationship between the electrical properties of a system and the concentration or activity of the analyte. Common electroanalytical methods include potentiometry, voltammetry, coulometry, and conductometry. Potentiometry involves measuring the potential difference of an electrochemical cell without significant current flow, often used to determine ion concentrations. Voltammetry studies the current as a function of applied potential, providing information about redox reactions and analyte concentration. Coulometry measures the total electrical charge passed during an electrochemical reaction, allowing for precise quantitative analysis. Conductometry, on the other hand, measures the electrical conductivity of a solution, which is influenced by the presence and mobility of ions. These techniques are widely applied in various fields such as environmental monitoring, pharmaceutical analysis, clinical diagnostics, and industrial process control due to their sensitivity, selectivity, and often low cost. The development of sophisticated electrochemical sensors and instrumentation has further expanded the utility and accessibility of elektroanalüütilised methods.
