"I would not hesitate to recommend it to anyone working in this field."Chromatographia
"Overall the coverage is a bit uneven - nevertheless the volume does compile some useful material... In conclusion, this is a comprehensive reference text, which should find its way into the libraries of all companies who are serious about process scale preparative chromatography, whether internally or via outsource contracts."
Organic Process Research and Development
"This special volume is essential for chemists and engineers working in chemical and pharmaceutical industries, as well as for food technologies, due to the interdisciplinary nature of these preparative chromatographic processes."

Persons
Prof. Seidel-Morgenstern is the Director of the Max Planck Institute for Dynamics of Complex Technical Systems, Magdeburg, Germany and holds the Chair in Chemical Process Engineering at the Otto-von-Guericke-Universität, Magdeburg, Germany. He received his Ph.D. in 1987 at the Institute of Physical Chemistry of the Academy of Sciences in Berlin. From there he went on to work as postdoctoral fellow at the University of Tennessee, Knoxville, USA. In 1994 he finished his habilitation at the Technical University in Berlin. His research is focused on New Reactor Concepts, Chromatographic Reactors, Membrane Reactors, Adsorption and Preparative Chromatography and Separation of Enantiomers amongst others.
Dr. Michael Schulte is Senior Director Emerging Businesses Energy at Merck KGaA Performance Materials, Darmstadt, Germany. In his Ph.D. thesis at the University of Münster, Germany he developed new chiral stationary phases for chromatographic enantioseparations. In 1995 he joined Merck and has since then been responsible for research and development in the area of preparative chromatography, including the development of new stationary phases, new separation processes and the implementation of Simulated Moving Bed-technology at Merck. In his current position one of his areas of research is the use of Ionic Liquids for separation processes.

System requirements:
- Computer (Windows; MacOS X; Linux): Install the free reader Adobe Digital Editions prior to download (see eBook Help).
- Tablet/smartphone (Android; iOS): Install the free app Adobe Digital Editions or the app PocketBook before downloading (see eBook Help).
- E-reader: Bookeen, Kobo, Pocketbook, Sony, Tolino and many more (only limited: Kindle).
The file format PDF always displays a book page identically on any hardware. This makes PDF suitable for complex layouts such as those used in textbooks and reference books (images, tables, columns, footnotes). Unfortunately, on the small screens of e-readers or smartphones, PDFs are rather annoying, requiring too much scrolling.
This eBook uses Adobe-DRM, a „hard” copy protection. If the necessary requirements are not met, unfortunately you will not be able to open the eBook. You will therefore need to prepare your reading hardware before downloading.
Please note: We strongly recommend that you authorise using your personal Adobe ID after installation of any reading software.
