Abstract

La présente invention concerne un procédé utilisé pour identifier des particules dans un milieu. Ce procédé consiste à introduire le milieu dans une chambre pouvant être évacuée, puis à irradier le milieu dans la chambre avec un rayonnement focalisé de densité de puissance prédéfinie, afin d'impliquer une fragmentation et ionisation quasiment totales d'au moins des petites particules dans le milieu, ce qui provoque la création d'espèces ionisées, notamment des ions à charges multiples, au cas où des particules sont présentes dans le milieu.
