Shrnutí	Voltammetry is an electrochemical analytical technique that studies chemical reactions and properties of substances by measuring the current response as the potential applied to an electrode is systematically varied. Developed by Jaroslav Heyrovsky in the 1920s (polarography), modern voltammetry has become essential for measuring redox potentials, detecting trace analytes, and investigating reaction mechanisms. Variants such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV) offer high sensitivity and selectivity for electrochemically active analytes.	Coulometry is an electrochemical analytical method that determines the concentration of an analyte by measuring the total electric charge (in coulombs) required to oxidize or reduce the analyte completely at an electrode. Developed by James J. Lingane in the 1940s, coulometry is highly accurate because it is based on fundamental constants (Faraday's law) and does not require external standards or calibration curves. This method is particularly valuable for trace analysis, water determination, and analysis of reactive species.	Ion chromatography is a liquid chromatography method that separates ions and polar molecules based on their relative affinity for the ion exchange resin in the column. Developed by Hamish Small in 1975, it combines ion-exchange separation with conductivity detection, enabling rapid, sensitive, and simultaneous determination of multiple ions in a single analysis. Ion chromatography has become an indispensable tool for monitoring environmental pollutants, analyzing food and pharmaceutical products, and studying complex ionic mixtures.
