The Database

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

Would You Like the E-Book?

Robert Adams has consistently updated the companion book to the database. The current edition, "Identification of Essential Oil Components by Gas Chromatography/Mass Spectrometry", ed. 4.1, contains all of the spectra, retention times, structures, and synonomy of the searchable database.

Although the database has carefully cataloged precise spectra and retention times for identification, the human eye is a powerful confirmation tool. The book is an additional important identification tool with the database.

The published book is out of print. The e-book is available for free, in appreciation to the many colleagues who have contributed to the Adams Library. Click on the button to request your free e-book.
