Compound library management instrument

With the advent of accurate mass instruments, access to a reference database or library of compounds with the exact masses of precursor and product ions is becoming increasingly important. Many instrument manufacturers, as well as independent companies or institutions, are developing software that allows chemists to manage this type of information for specific applications such as proteomics or chemical contaminants. Examples of online resources that may be useful for searching for unknown residues based on molecular formulas obtained from accurate mass data inciude Metlin from the Scripps Center for Mass Spectrometry and ChemSpider from the Royal Society of Chemistry.
