The in-depth study concerned with the separation, quantification and identification of matter using different methods and instruments is called analytical chemistry. The different concepts and methods used under this field can be divided into two broad categories namely, classical qualitative methods and classical quantitative methods. Qualitative analysis involves the determination of the presence or absence of specific compounds. Kastle-Meyer test, acid test and flame test are examples of qualitative methods used in analytical chemistry. Quantitative analysis measures the quantities of chemical constituents which are present in a substance. It includes volumetric and gravimetric analyses. Spectroscopy, electrochemical analysis, thermal analysis, microscopy, hybrid techniques, etc. are some of the instrumental methods of use in analytical chemistry. Some of its primary applications are in the areas of environmental analysis, forensic science, materials analysis, bioanalysis, etc. This book discusses the fundamentals as well as modern approaches of analytical chemistry. It will serve as an essential guide for both academicians and those who wish to pursue this discipline further.
