Glossary Flow Injection Analysis

technique for analyzing substance concentrations in samples

Flow Injection Analysis (FIA) is a technique used in chemistry to analyze the concentration of substances in a sample. It involves injecting a small volume of the sample into a continuously flowing carrier stream, which then passes through a detector that measures the desired analyte. This method is efficient and allows for rapid, automated analysis of multiple samples.
