Beginning with a thorough discussion of the fundamental theories and physics of ion mobility, this third edition reference follows the traditional organization of the original, beginning with fundamental theories and physics of ion mobility. It then moves on to the recent advances in instrumentation and newly pioneered applications. Each chapter is thoroughly updated, with new information on present trends in IMS and coverage of FAIMS and DMS/MS. Significant expansion to the Biological and Biomedical section is provided, with an emphasis on LC ESI Mobility MS or ESI Mobility MS, including IMS TOF. The previously included CD-ROM is now available as a webpage for qualified instructors.
