Title (EN) QUADRUPOLE DEVICES
(FR) DISPOSITIFS QUADRUPÔLES
Abstract:
(EN) A method of operating a quadrupole device is disclosed that comprises operating the quadrupole device in a first mode of operation, and operating the quadrupole device in a second mode of operation. Operating the quadrupole device in the first mode of operation comprises applying one or more first voltages to the quadrupole device such that the quadrupole device is operated in an initial stability region and such that at least some ions are stable within the quadrupole device. Operating the quadrupole device in the second mode of operation comprises applying one or more second voltages to the quadrupole device such that the quadrupole device is operated in a different stability region and such that at least some of the ions that were stable within the quadrupole device in the first mode of operation are stable within the quadrupole device in the second mode of operation.
(FR) L’invention concerne un procédé de commande d’un dispositif quadrupôle qui consiste à commander le dispositif quadrupôle dans un premier mode de commande, et à commander le dispositif quadrupôle dans un deuxième mode de commande. La commande du dispositif quadrupôle dans le premier mode de commande consiste à appliquer une ou plusieurs premières tensions du dispositif quadrupôle de sorte que le dispositif quadrupôle est commandé dans une zone de stabilité initiale de sorte que des ions sont stables dans le dispositif quadrupôle. La commande du dispositif quadrupôle dans le deuxième mode de commande consiste à appliquer une ou plusieurs deuxièmes tensions au dispositif quadrupôle de sorte que le dispositif quadrupôle est commandé dans une zone de stabilité différente de sorte qu’au moins une partie des ions qui étaient stables dans le dispositif quadrupôle dans le premier mode de fonctionnement sont stables dans le dispositif quadrupôle dans le deuxième mode de fonctionnement.
