Description

Filling a gap in the literature for a hands-on guide focusing on everyday laboratory challenges, this English edition has been expanded and revised using the feedback received on the successful German precursor. Throughout the book, Professor Mascher draws on his 30 years of
experience and provides abundant practical advice, troubleshooting and other hints highlighted in boxes, as well as a broad selection of walkthrough case studies. Based on a course taught by the author, the first part of the book intuitively explains all steps of routine bioanalysis and explains how to set up a robust, inexpensive and effi cient method for a given substance. In the second part he includes 20 worked example cases that highlight common challenges and how to overcome them.

With its appendix containing tried-and-tested analytical methods for 100 clinically relevant substances from the author`s own laboratory,
complete with spectral and MS data as well as literature references and basic pharmacokinetic information, this is a life-long companion for
everyone working in clinical, pharmaceutical and biochemical analysis.

Comments to the German book:
"The book comes to life through its examples, showing not only what did work in the author's laboratory, but also what didn't."
ChemieReport

"Indispensable for novices, while even old hands will be able to expand their knowledge. A collection of analytical data for ca. 100 substances completes the book's offering, leaving almost nothing to be desired."

Author Information

Hermann Mascher is founder and CEO of the independent contract research organization "pharm-analyt" based in Baden (near Vienna), Austria. A chemist by training, he has been dealing with quantitative determination of drugs, metabolites, phyto-ingredients and endogenous substances in plasma, urine and tissue for more than 30 years. Professor Mascher is regularly being consulted for analytical questions
of drugs, food as well as botanical and ecological issues. He has published over 80 publications majorly in peer reviewed journals and received several awards in science and innovation for his work in the analysis of clinically important substances.

Reviews

"The book is clearly written and comprehensive. A lot of practical advice and tips makes it helpful for any practically oriented clinical laboratory and it can be counted as a valuable source for everyone working with chromatographic techniques in a bioanalytical laboratory."  (Analytical and Bioanalytical Chemistry, 13 November 2012)

“This book is more than a very successful and useful user guide, and is a valuable tool for the laboratorywork, not only for clinical analysts, but also for biochemists, pharmacists, etc. In addition to a compact targeted representation of the most important theoretical foundations for the planning and execution of (clinical) analysis (sample preparation, HPLC separation, usage of different modes, detection capabilities, derivatization techniques to the point of validation), the readers receive valuable information for their work, which are explained on the basis of practical examples [pages 1–64].”  (ChemMedChem, 1 November 2012)
