책소개

This book provides a comprehensive up-to-date overview of temperature-programmed gas chromatography (GC). The first part of the book introduces the reader to the basics concepts of GC, as well as the key properties of GC columns. The second part describes the mathematical and physical background of GC. In the third part, different aspects in the formation of a chromatogram are discussed, including retention times, peak spacing and peak widths. An invaluable reference for any chromatographer and analytical chemist, it provides all the answers to questions like:* At what temperature does a solute elute in a temperature-programmed analysis? * What is the value of the retention factor of eluting solute? * How wide are the peaks? * How large is the time distance between two peaks? * How do all these parameters depend on the heating rate?

출판사 서평

“It best serves as a reference book on GC theory and, at that, it probably is the best one out there. I expect I will continue to use this book for many, many years to come and I recommend it to anyone using GC for anything more than the simplest of purposes.”& (Journal of Chemical Education, 18 November 2012)&

Leonid M. Blumberg obtained his academic degrees in electrical engineering and training in mathematics from leading institutions of higher education in St. Petersburg, Russia. In 1977, he immigrated to USA and joined Hewlett-Packard Co. as an electrical engineer. Later he became a resident theoretician responsible for optimization of GC instrumentation and analytical methods. In this capacity, he participated in defining several new GC instruments. After leaving HP in 1998, Dr. Blumberg founded a consulting company, Fast GC Consulting, and continued the development of theoretical foundation for optimization of conventional, fast and multi-dimensional GC where he is a world leading expert.Leonid Blumberg authored 50 scientific publications and patented 19 inventions.
