The practice of identification, separation and quantification of matter is under the scope of analytical chemistry. Such analyses can be qualitative or quantitative. Qualitative analysis identifies analytes whereas quantitative analysis determines numerical concentration of the analytes. Separation techniques of precipitation, distillation and extraction, and wet chemical and classical methods are commonly used. Improvements in experimental design, creation of new tools of measurement and chemometrics are significant aspects of analytical chemistry. This textbook aims to shed light on some of the unexplored aspects of analytical chemistry. It elucidates new techniques and their applications in a multidisciplinary approach. In this book, constant effort has been made to make the understanding of the difficult concepts of analytical chemistry as easy and informative as possible, for the readers.
