Σύνοψη	Flow injection analysis is an automated continuous-flow technique that rapidly injects a sample plug into a flowing stream of carrier solution, where it mixes with reagents and is detected online before reaching the detector. Developed by Jaromir Ruzicka and Elo Hansen in 1975, FIA revolutionized analytical chemistry by enabling rapid, high-throughput analysis with minimal reagent consumption and waste. Flow injection analysis is widely used in pharmaceutical, food, environmental, and clinical laboratories for routine quantitative analysis.	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.
