Ever wish that there was a large MS/MS library to help identify unknown compounds observed by LCMS? That would make identification by LCMS as easy as GCMS.

Our company has developed a pattern matching approach that compares accurate-mass fragmentation data directly against a large database of small molecules (represented as "rows" of mathematical partitions) to find matching compounds. Traditional mass spectral libraries are no longer needed. Advances in mass spectrometers and computers have made this breakthrough possible. This is the ideal solution for identifying many types of small molecules: drugs, indigenous metabolites, food adulterants, packaging components, additives, and natural products. The Rational Numbers™ searchable database of partitions resides on our server; all you need is your accurate-mass fragmentation data and any web browser. See Pattern Matching.

In the battle between numbers and humans, we just launched a simple Excel® Add-In that every mass spectrometrist who does identification work should have. Traditional mass-intensity graphs date back to the 1940s when spectra were recorded on light pen recorders. Today this Excel Add-In rapidly transforms accurate-mass fragmentation data into a structure-orientated graphical format. This Add-In, which includes some new mass spectral functions for Excel, is a great tool for identifying proprietary reaction products, impurities, degradation products, and metabolites. See Pattern Recognition.
