"Mark Vitha has written a book that will appeal to students, teachers, and perhaps professional analysts who need a refresher in the fundamentals of chromatography. The book consists of three sections of about equal length dealing with separation theory, gas chromatography (GC), and liquid chromatography (LC). The section on theory is especially strong. Vitha is an experienced educator who understands the undergraduate audience and explains concepts clearly. He uses analogies to help students with abstract ideas, something I have seen little of in the sciences. He also freely uses ideas and terms from thermodynamics that can be grasped by students who have studied physical chemistry". "Graduate students might want to use this book, with additional depth provided by their instructors and current and classic papers (many are referenced). Graduate students need more depth in areas such as solvent theory and the selection of solvents, for example, than is given in this book". "I taught instrumental methods to undergraduate students for many years using encyclopedic full-course texts. I wish there had been as fine a pedagogical tool as this more-focused new textbook at that time". (LC/GC- December 16)
