Abstract

On présente un spectromètre de masse comportant une première région de champ électrique A mass L2 dans laquelle un champ électrique variable dans le temps est appliqué. Dans un certain mode de fonctionnement, un influx d'ions (3) composé d'ions de différents rapports masse/charge traverse la région de champ électrique L2, et on fait varier le champ électrique dans le temps de manière à ce qu'au moins certains des ions (3) ayant différents rapports masse/charge parviennent dans la région d'extraction ou d'accélération (10) d'un analyseur de temps de vol essentiellement au même moment.
