PRINCIPLES OF INSTRUMENTAL ANALYSIS is the standard for courses on the principles and applications of modern analytical instruments. In the 7th edition, authors Skoog, Holler, and Crouch infuse their popular text with updated techniques and new Instrumental Analysis in Action case studies. Updated material enhances the book's proven approach, which places an emphasis on the fundamental principles of operation for each type of instrument, its optimal area of application, its sensitivity, its precision, and its limitations. The text also introduces students to elementary analog and digital electronics, computers, and the treatment of analytical data. A companion website is available, providing students with tutorials on instrumental methods, Excel files of data analysis, and simulations of analytical techniques to help them visualize important concepts. Digital Object Identifiers (DOIs) are provided for most references to the primary literature.

All Chapters Have Been Revised And Updated With Recent References To The Literature Of Analytical Chemistry. Throughout The Book, New And Updated Methods And Techniques Are Described, And Photos Of Specific Commercial Instruments Have Been Added. Modern Topics Include Laser-Based Spectrometry, fluorescence Quenching And Lifetime Measurements, Tandem Mass Spectrometry, And Biosensors.New Or Updated Instrumental Analysis In Action Features Appear At The End Of Each Section. One Of The New Case Studies Discusses The Bisphenol A Controversy And The Role Of Chromatography In This Environmental Problem. The Second New Case Study Covers The Role Of Neutron Activation Analysis In The Many Investigations Of The John F. Kennedy Assassination. The Case Studies Expand On The Methods Introduced In Each Section And Show How They Can Be Applied To Specific Analytical Problems. These Stimulating Examples Have Been Selected From The Forensic, Environmental, And Biomedical Areas.Because Many Instrumental Techniques Have Been Or Are Being Used In Nasa'S Exploration Of Mars, The Authors Present The Principles And Applications Of These Methods Where Appropriate.Chapter 7, "Components Of Optical Instruments," Includes Updated Information On Laser Sources, Array Transducers, And Ft Instruments.Chapter 10, "Atomic Emission Spectrometry," Contains New Information On Plasma Spectrometers Including Multi-Channel, Array Detector Systems, And Laser-Based Plasma Instruments.
