Analytical chemistry focuses on electrochemical methods quality assurance, qualitative analysis, quantifying nature, quantitative analysis, gravimetric methods, evaluating analytical data, spectroscopic methods and Standardizing analytical methods. The science of obtaining, processing and communicating information about the composition and structure of matter is called Analytical Chemistry. It is the art and science of determining matter and how much of it exists. The separation techniques involved in the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of qualitative analysis and quantitative analysis of species in an immense variety of settings. Analytical chromatography will be used in various fields for separation and analytical biochemistry is used to detect various samples.
