Linden CMS manufactures and markets LIFDI, one of the softest ionization techniques for Mass Spectrometry. It is performed within minutes. It is sensitive and easy to use even for air/moisture sensitive samples. LIFDI forms intact molecular ions of e.g. organometallic complexes, non-polar hydrocarbons, crude oils and sterically hindered samples. LIFDI gives meaningful mass spectra from difficult samples inaccessible to analysis by established techniques.
