Scientific work at several universities like Innsbruck (Austria), Boulder (USA), Southampton (UK), Paris (France), Greifswald (Germany), Trento (Italy) led to the development of instruments to simulate reactions of atoms and molecules in space (interstellar clouds).
These research works were the prerequisites for the Ion-Molecule Reaktion Mass Spectrometry (IMR-MS) which is the core technology used for most of the V&F Analyzers. Today IMR is one of the most sensitive techniques to detect impurities in gases.
