What is analytical chemistry?

Analytical chemistry is the branch of chemistry that provided the methods for identification of the substance, determination of structure, and quantitative analysis of the composition of matter. It is widely applicable in the various disciple of chemistry such as inorganic, organic, physical, and biochemistry.

Analytical methods are also applicable in the fields of environmental science, agricultural science, biomedical, clinical chemistry, forensic, and space research. In this category, we provide an introduction and different topics related to analytical chemistry.
