Analytical Chemistry
Analytical chemistry is the science that studies the composition, structure, properties, content and distribution of substances. It not only focuses on the qualitative (what is the substance) and quantitative (how much of the substance is there) chemical composition, but also includes the analysis and determination of samples through various analytical techniques and methods. Analytical chemistry is an important branch of chemistry and is widely used in many fields such as environmental monitoring, food safety, medical diagnosis, drug development, and materials science.
