"It was my great pleasure to read this clearly written and well organized mass spectrometry (MS) book. In view, it can serve as an excellent textbook for both undergraduate and graduate students who major in analytical, biological, forensic, or environmental chemistry, as well as a valuable resource to those researchers who are interested in the MS-based chemical analysis." (J Am Soc Mass Spectrom, 2011) "The book is particularly designed for graduate students, with the assumption being made that most of them will not become mass spectrometry specialists. Instead, it focuses on how they can use the technique to support and advance research across a broad range of disciplines." (Chemistry Journals, 11 April 2011)
