Principles of Analytical Chemistry aims to ease the first contact of students pursuing different scientific and technical studies by providing them with a simple, general overview of the discipline. The objective of this innovative textbook is to teach rather than to inform. Using keywords of modern Analytical Chemistry, it constructs a teaching message accessible to the beginner, with emphasis on relations between these keywords to ensure consistency in the teaching contents of the book. Practical exercises, 450 questions for students, and 27 interactive seminars are used as vehicles for expounding a large number of examples in order to clarify and consolidate the text and facilitate its comprehension.
