תקציר	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.	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.	Potentiometric titration is an electrochemical method of analysis that measures the potential difference between a reference electrode and an indicator electrode as a titrant is gradually added to a solution. Developed in the early 20th century, it allows precise determination of the concentration of analytes without requiring visual endpoint indicators. This method is fundamental in analytical chemistry for determining acids, bases, redox species, and metal ions.
