Chemistry is a natural science, which is involved with the study of elements and compounds, their structures, properties, composition, behavior and reactions with other substances. The branch of chemistry that deals with the separation, identification and quantification of matter is known as analytical chemistry. Such analyses of material samples help in understanding of chemical structure and composition. This can be performed through various classical or wet chemical methods as well as modern or instrumental methods. Separation of materials is possible through processes like distillation, extraction and precipitation, or through electrophoresis, chromatography or field flow fractionation. Material analysis usually employs the interaction of the material with light, heat, and electric and magnetic fields. Such analytical methods have major applications in the fields of science, engineering, forensics and medicine. This book contains some path-breaking studies in modern analytical chemistry. Also included is a detailed explanation of the various analytical methods of chemistry and their applications. It is an essential guide for both academicians and those who wish to pursue this discipline further.
