Essential Oil Components by GCMS

The Essential Oils by GC/MS database was born over 40 years ago, when Professor Robert P. Adams began his research on terpenes, and populated the database with his research and the contributions of dozens of respected plant biologists around the world.

Version 4 of the Terpene database now includes the spectra and retention times for 2,205 compounds. This product includes a searchable database in either Agilent or NIST compatible formats and an electronic copy of the book “Essential Oil Components by GC/MS” with spectra, retention times, structures, and more.
