| Sintesi≠ | 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. | UV-Vis spectrophotometry is an optical analytical technique that measures the absorption of ultraviolet and visible light (wavelengths 190–900 nm) by substances in solution. Founded on the Beer-Lambert law (developed by August Beer and Pierre Bouguer), it is one of the oldest and most widely used quantitative analytical methods. UV-Vis spectrophotometry is economical, rapid, and applicable to a vast range of organic and inorganic compounds, making it indispensable in pharmaceutical, clinical, environmental, and research laboratories. |
