Compositional analysis is a research area that focuses on studying the structure, properties, and behavior of substances based on their chemical composition. This field typically involves the use of analytical techniques to identify and quantify the individual components present in a sample, such as food, pharmaceuticals, or environmental samples. Compositional analysis aims to provide valuable insights into the makeup of materials, leading to a better understanding of their characteristics and potential applications. Researchers in this area often employ various analytical techniques, such as chromatography, spectroscopy, and mass spectrometry, to analyze samples and determine their composition accurately. Overall, compositional analysis plays a crucial role in numerous industries, including food and beverage, pharmaceuticals, environmental monitoring, and materials science, by ensuring product quality, safety, and compliance with regulations.
