Agilent Fiehn GC/MS Metabolomics RTL Library Product Note introduces the features and usage of this product
The Agilent Fiehn GC/MS Metabolomics RTL Library is a comprehensive resource containing searchable EI spectra and retention time indexes for approximately 700 common metabolites. Developed with Dr. Oliver Fiehn, the library includes entries for partially derivatized metabolites to facilitate positive identification in untargeted metabolomics research. It is supplied with complete, preprogrammed GC/MS methods and integrates with Agilent's software tools for faster metabolite identity determination.
The library supports identification using the ChemStation software's native probability-based matching (PBM) algorithm and the AMDIS automated GC/MS identification program from the U.S. National Institute of Standards and Technology. It also utilizes retention indexing and retention time locking to increase confidence in search results, reducing run-to-run retention time variation. The library is compatible with Agilent 6890 or 7890 GC systems and 5973 or 5975 MSD instruments.
