Abstract :
[en] Reduction process is widely observed in LSIMS/FAB spectrometry when radical producing matrices are used. This phenomenom strongly alters the expected isotopic intensity distribution of the molecular ion. The extent of chemical damage depends on the solute concentration. On the other hand, it can be taken advantage of the reduction process because the oxidized and reduced molecular forms exhibit different fragmentation pattern. Helpful structural information can be infered from these MS/MS data.
