Practical High-Performance Liquid Chromatography

• Broschiertes Buch

Produktbeschreibung

This textbook aims to present the knowledge which is necessary for everyday HPLC measurements to be made, in a detailed and easy-to-follow manner. It contains a wealth of practical material and covers a wide range of subjects. Topics covered include principles, instrumentation, reverse-phase, ion-exchange, ion-pair, ion, size-exclusion and affinity chromatography, as well as analytical methods, preparative HPLC and enantiomeric separations. Appendices provide information on instrument testing, troubleshooting, column-packing.

Jump into the HPLC adventure!

Three decades on from publication of the 1st German edition of Veronika Meyer's book on HPLC, this classic text remains one of the few titles available on general HPLC aimed at practitioners.

New sections on the following topics have been included in this fifth edition:
Comparison of HPLC with capillary electrophoresis
How to obtain peak capacity
van Deemter curves and other coherences
Hydrophilic interaction chromatography
Method transfer
Comprehensive two-dimensional HPLC
Fast separations at 1000 bar
HPLC with superheated water

In addition, two chapters on the instrument test and troubleshooting in the appendix have been updated and expanded by Bruno E. Lendi, and many details have been improved and numerous references added.

A completely new chapter is presented on quality assurance covering:
Is it worth the effort?
Verification with a second method
Method validation
Standard operating procedures
Measurement uncertainty
Qualifications, instrument test, and system suitability test
The quest for quality

Reviews of earlier editions

"That this text is written by an expert in both the practice and teaching of HPLC is evident from the first paragraph....not only an enjoyable, fascinating and easy read, but a truly excellent text that has and will serve many teachers, students and practitioners very well." --The Analyst

"...provides essential information on HPLC for LC practitioners in academia, industry, government, and research laboratories...a valuable introduction." - American Journal of Therapeutics
