Analytical chemistry is the study and use of instruments and methods for separating, identifying, and quantifying materials. Separation, identification, and quantification may be used alone or in combination with other methods in practice. Classical wet chemical procedures and current instrumental methods constitute analytical chemistry. Improvements in experimental design, chemometrics, and the development of novel measuring equipment are objectives of analytical chemistry. Analytical chemistry is used in a range of contexts, including medicine, science, and engineering.
Synthetic chemistry is the study of the relationship between organic molecule structure and reactivity. Physical-chemical science, in particular, uses chemical research's experimental capabilities to the study of the structure of organic molecules and provides a theoretical framework. Organic, inorganic, materials, and even biological sciences are all covered under synthetic chemistry.
