Instrumental analytics provides a lens of understanding through the developed methods and examination procedures. These procedures are the subject of this practical textbook, which aims to convey the fundamentals, as well as the applications and latest developments, to students, lecturers, developers, and practitioners. A key focus of the book is on quality assurance, which, due to Cammann's experiences as a lecturer and equipment developer, is presented clearly and up-to-date, holding significant importance unlike any other analytics textbook.
