A method is provided of operating a mass spectrometer having first and second rod sets, which can be a focusing set of rods and an analysis rod set, the second rod set being downstream from the first rod set at an outlet of a spectrometer. Ions are directed into the first rod set and an RF voltage applied to the two rod sets, the RF voltage can be the same or different for the two rod sets. A low level DC voltage is applied to the first rod set sufficient to reduce a continuum background ion signal, thereby to increase the signal-to-noise ratio of the spectrometer.

L'invention se rapporte à un procédé de mise en oeuvre d'un spectromètre de masse comportant un premier jeu et un second jeu de tiges, qui peuvent être un jeu de tiges de mise au point et un jeu de tiges d'analyse, le second jeu de tiges étant disposé en aval du premier jeu de tiges, au niveau d'un orifice de sortie du spectromètre. On dirige les ions dans le premier jeu de tiges et l'on applique une tension R.F. aux deux jeux de tiges, la tension R.F. pouvant être identique ou différente pour les deux jeux de tiges. On applique au premier jeu de tiges une tension C.C. de bas niveau suffisante pour réduire un signal des ions du fond du spectre continu de manière à accroître le rapport signal-bruit du spectromètre.
