| titleOfInvention | Multipole ion guide ion trap mass spectrometry. |
| abstract | (57) [Summary] A time-of-flight mass spectrometer is a multipole ion guide (16) located in an ion flight path between an ion source (1) and a flight tube (42) of the time-of-flight mass spectrometer. Is provided. In one preferred embodiment, the time-of-flight (TOF) mass spectrometer has a multipole ion guide located in the ion path between the ion source (1) and the ion pulsing region (30) of the TOF mass spectrometer. It is configured to make it. The electronics of the multipolar ion guide and the entrance and exit electrostatic lenses (26, 27 and 28) of the ion guide are configured to allow trapping or passage of ions supplied from an atmospheric pressure ion source. The electronics of the ion guide can be set to select the mass to charge (m / z) range of ions that can be successfully transmitted or trapped in the ion guide. More than two sets of m / z values can be selected, for example, using techniques such as notch filtration by resonant frequency ion extraction of unwanted m / z values. All or a portion of the ion guide trajectory, which is then stable in a transfer or trap manner, can undergo collision induced dissociation (CID) using one of at least three techniques. During the ion fragmentation step, the multipole ion guides AC and DC potentials are set to transfer or trap all or part of the fragment ions generated by the CID process. All or part of the parent and fragment ion populations are supplied from the multipole ion guide to the pulsed region of the time-of-flight mass spectrometer for mass analysis. After the first ion fragmentation step, the multipolar ion guides AC and DC potentials are set again to select a narrow m / z range for clearing the ion guide by trapping all fragment ions other than the selected group. it can. The m / z selection and ion fragmentation process with repeated many times, give rise at various points upon gradual process ends or when MS / MS n for all MS / MS n process the mass spectrometry. The regular stepwise MS / MS n analysis capabilities is united in a single step is also disclosed technique can increase the effective repetitive use. The multipolar ion guide used for ion transfer, trapping and fragmentation can be in one voltage pumping step (138) or extend continuously to two or more vacuum pumping steps (18, 19). You can also. |
