Identification of Essential Oil Components by Gas Chromatography/Mass Spectrometry, 4th Edition
 Author: Robert P. Adams, PhD
  • Hardcover
  • 804 Pages
  • Published 2007
  • Summary:



    With GC/MS still the preferred method of essential oil analysis, Dr. Adams's book is as relevant and useful as ever. This 4th edition is the most up-to-date and comprehensive yet!

    Since it is impossible to identify some terpenes by mass spectrum only, the Adams library with retention times and Kovat's indices is the only terpene library that one can use to identify more than 95% of the components in common essentials oils with certainty. A comprehensive collection of mass spectra and retention times of common components in plant essential oils, this reference covers 2,205 compounds, each including:

    • RT—retention time on DB-5 capillary column
    • AI—arithmetic retention index
    • KI—Kovat's retention index
    • CAS#—chemical abstracts service number
    • MF—molecular formula
    • FW—formula weight
    • MSD LIB#—entry number in library
    • CN—chemical name
    • List of synonyms
    • Source of compound used for spectrum. If the compound occurs in nature, two additional sources for the compound (concentration at % oil, plant name, literature reference) are included.

    All 2,205 compounds have been analyzed from their original sources on an HP5971 MSD mass spectrometer using HP Chemstation software. In addition, the library (including retention times) is now available for the most common mass spectrometer/computer systems.

    The 4th Edition now includes:

    • An additional 600 compounds
    • 2,205 compounds analyzed from their original sources
    • Larger and easier to read mass spectra
    • Occurrence nature information
    • 37% more content than the 2001 3rd Edition!
