CEU Mass Mediator is a tool for searching metabolites in different databases (Kegg, HMDB, LipidMaps, Metlin and an in-house library). This is specially designed for searches through experimental mass obtained from mass spectrometry techniques.

CEU Mass Mediator includes an advanced search which could be used to identify adducts from different ionization modes using the CompositeSpectrum from Agilent Software. It unifies compounds from different sources. It will save time to researches which have to find the compounds in the databases one by one and unifying them manually. It avoids the risk of unify different compounds by human errors.

CEU Mass Mediator version 2.0.
