The field of chemistry concerned with the study and use of instrumental and classical methods for the analysis of matter is known as analytical chemistry. It encompasses the separation, identification and quantification of matter. Separation processes include classical methods, such as distillation, precipitation and extraction, as well as instrumental methods of chromatography, field flow fractionation and electrophoresis. Modern analytical chemistry builds on the classical techniques of qualitative and quantitative analyses. These include chemical and flame tests, gravimetric analysis and volumetric analysis. This discipline is aided by several instrumental methods, which include spectroscopy, thermal analysis, electrochemical analysis, etc. This book presents the complex subject of analytical chemistry in the most comprehensible and easy to understand language. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included herein. It will prove to be immensely beneficial to students and researchers in this field.
