Reviewed in Journal of the American Chemical Society 2003, 125, 10144-10146 by David J. Butcher, Western Carolina University, USA "I am happy to report that this volume is even better than the original... In general. the book is an excellent source of information on all aspects of chromatography... It is not simply a revision of Chromatography Today; most chapters have been completely rewritten, and several new topics have been introduced... In summary, I highly recommend this volume." Reviewed in LC-GC Europe, Vol 16, No.5, May 2003 by Geoff Potter, University of the West of England, Bristol, U.K. "The book is a "must" for all libraries. A reference work that will remain authoritative for many years." Reviewed in CHOICE, September, 2003 by H. T. McKone "Highly Recommended. Graduate students through professionals." Reviewed in CHEMISTRY IN AUSTRALIA, May, 2003 by Philip Marriott FRACI, Australian Centre for Research on Separation Science, RMIT University, Melbourne, Australia "Quite simply, Colin Poole has again produced a text that is authoritative, comprehensive, informative, and an excellent source as a one-stop reference to the field of separation science." Reviewed in CHROMATOGRAPHIA, Vol. 57, 2003 by P. Myers "Overall this is a well-planned book, very well written and one that should become the prime standard for anyone entering chromatography or simply wanting to understand a little more about a different area of the subject." Reviewed in TrAC, by F. Svec, University of California, Berkeley, USA "Colin Poole deserves to be cheered for his excellent work. The Essence of Chromatography contains all the important information that chromatographers - both novices and professionals alike - may need for rapid orientation as well as for an in-depth understanding of the discipline. Therefore, this book ought to be available in all libraries that serve universities and companies that teach, develop, or practice chromatography. I would even recommend that those who are active in the field of chromatography have their own copy on their bookshelves. I am sure that this book is one which will remain in use for a long period of time."
