Analytical Chemistry is a branch of chemistry focused on the qualitative and quantitative analysis of substances. It involves techniques and methods to determine the composition of materials, which is essential in various fields such as pharmaceuticals, environmental science, and food safety. Analytical chemists use instruments like mass spectrometers and chromatographs to identify and measure chemical compounds. The discipline plays a crucial role in research and development, ensuring that products meet safety and quality standards. By employing statistical methods and rigorous testing, analytical chemistry helps in making informed decisions in industries ranging from healthcare to manufacturing.
