Abstract

L'invention concerne un procédé permettant d'extraire des ions, consistant : à préparer une source d'ions ; à entraîner ces ions dans un flux laminaire d'un gaz vecteur ; à préparer une région barrière dans laquelle un champ électrique est appliqué sur le flux laminaire de gaz vecteur, la magnitude et la direction du champ électrique étant choisies de manière à empêcher au moins certains des ions entraînés dans le flux laminaire de traverser le champ électrique ; et à modifier le champ électrique de façon à permettre à des ions qui présentent des caractéristiques choisies de traverser le champ électrique
