Analytical chemistry is a branch of chemistry that focuses on the study of the composition of matter, and the methods used to examine chemical compositions.
Analytical chemists use a variety of techniques and methods to identify and quantify the components of a sample, often down to trace levels. These methods can range from simple qualitative tests to highly sophisticated instrumental methods giving quantitative chemical information.
Analytical chemistry has a wide range of applications across various industries and scientific disciplines. It is used in environmental monitoring, pharmaceutical analysis, food and beverage testing, forensic science, clinical diagnostics, materials characterization, and more. The data generated through analytical chemistry are essential for quality control, research, regulatory compliance, and decision-making in numerous fields.
