Forensic chemistry is an essential field that connects science and justice. It uses analytical methods and chemical principles to identify chemicals, solve crimes, and produce important evidence for court cases. The goal of this textbook is to give researchers, students, and forensic experts a thorough understanding of how chemistry plays a part in forensic investigations. Important subjects covered in this book include General forensic science, Chemical analysis of finger prints, chemical analysis of explosives, examination of drugs and applications of instrumentation in forensic science. A solid basis in forensic chemistry techniques, equipment, and real-world case applications is intended to be established by each chapter. Modern analytical methods that are crucial in forensic labs, like mass spectrometry, spectroscopy, and chromatography, are given special attention. This book aims to foster critical thinking and useful problem-solving abilities in addition to imparting knowledge. Readers will learn about the duties and difficulties faced by forensic chemists through case studies, lab procedures, and ethical considerations.
