Title: Improved use method of ion trap mass spectrometer
Inventor: WELLS GREGORY J
IPC: H01J49/42
Filed: 2003-05-22
Abstract: <P>PROBLEM TO BE SOLVED: To remove a sample ion generated in an ion trap during the ionization of a reagent gas without the need for changing an RF trapping field between ionization and reaction processes.  <P>SOLUTION: A broadband auxiliary AC voltage is applied to remove ions above or below a predetermined cutoff mass. A high mass sample ion is removed which is generated when a sample gas is ionized by electronic ionization, or a low mass sample ion is removed when an electronic ionization experiment is carried out in the presence of the sample gas. A non-resonance, low-frequency, auxiliary voltage is applied to the ion trap in order to subject an ion-trapped ion to collisional-induced dissociation. The multiple generation of ion fragments is simultaneously formed using this method to enable the MS<SP>n</SP>experiment. The low frequency auxiliary field has an additional property of jumping the high mass ion out of the ion trap as a function of the magnitude of the auxiliary voltage, and can be used to scan the magnitude of the auxiliary voltage or remove undesirable sample ions.  <P>COPYRIGHT: (C)2004,JPO
