These instruments allow to study the fundamental processes that govern the fate of various components of atmospheres or those present at the land/atmosphere interface. In general, the experimental approach is to inject compounds in reactors, and follow their evolution (nature and abundance of formed products…). Provided that the conditions of the environment are reasonably reproduced (T °, irradiation, concentrations,...), the results obtained in terms of kinetics and reaction mechanism are transposable to the natural environment. This approach implies the use of original instruments equipped with suitable analytical tools.

Therefore, LISA developed experimental simulation tools to characterize one or more parameters in a "controlled" environment :
