This book provides a comprehensive introduction to modern analytical chemistry with a strong focus on instrumental techniques and practical methods. It covers the principles, working mechanisms, and applications of key analytical instruments such as spectroscopy, chromatography, thermal analysis (TGA, DTA), and elemental analysis. Designed for undergraduate and postgraduate students, the text bridges theory with real-world laboratory practice, emphasizing data interpretation, accuracy, and method selection. Richly illustrated and concept-driven, the book serves as an essential resource for chemistry students, researchers, and professionals in pharmaceuticals, materials science, environmental analysis, and industrial quality control. 
This textbook explains the fundamental concepts and working principles of analytical instruments commonly taught in chemistry curricula, supported by diagrams, spectra, and thermal curves for easy understanding and exam preparation.
