LIPIDS Mass Spectral Database

LIPIDS Mass Spectral Database

The Lipids Mass Spectral Database contains 430 mass spectra, with structures for 428 compounds obtained from pure standards and categorized into 11 lipid classes. This library has been extensively validated to ensure positive lipid identification; the database includes a total of over 1400 linear retention index (LRI) and equivalent chain length (ECL) values on three phases, providing significant support for peak assignment in complex mixtures.

Lipids is invaluable to speed up FAME identification, peak annotation and quantitative workflows. This should be an essential tool for all laboratories determining FAMEs, from R&D to routine QC analysis.

Over 1,400 Linear Retention Index (LRI) values for the 430 lipid-like molecules, experimentally calculated for each standard under repeatable chromatographic conditions using three different stationary phases, namely SLB-5ms, Equity-1, and Supelcowax-10 (Supelco). LRI were also calculated using different reference mixtures, namely alkanes, fatty acid methyl esters (FAMEs), and fatty acid ethyl esters (FAEEs). Additional component information such as CAS number, common name, systematic name, nominal mass (as Mol Wt.), compound formula, chemical class, and suppliers of the standards are also included.
