Short Introduction:

The Seven Golden Rules are used on our laboratory to overcome the problem of wrong molecular formula
assignments from LC-MS, GC-MS, FT-ICR-MS data. They were developed for research and advances in structure elucidation of small molecules. Follow the navigation on the left for some additional comments and experimental data.
