MSP Kofel provides analytical scientists with software and databases for interpretation, confirmation and archival of spectra and chromatographic data. Since the early 1970s the MassLib™ software is one of the leading tools for the evaluation of mass spectra, e.g. GC-MS, thermal desorption, LC-MS, etc. Combining a variety of powerful searches for spectra, isotopic patterns, structures and data, with a convenient and efficient user interface make MassLib an ideal tool for the analysis of chromatography / mass spectrometry data, and particularly for structure elucidation of small molecules, metabolites and unknown compounds with no library reference.
