Identification of Essential Oil Components by Gas Chromatography/ Mass Spectrometry, 4th Edition

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!
A comprehensive collection of mass spectra and retention times of common components in plant essential oils, this reference covers 2,205 compounds.

Every compound includes:

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
Synonyms—list of synonyms
Source—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.
