A second Wien filter focuses the electron beam to become parallel in the first plane while leaving the electron beam to be parallel in the second plane. Other embodiments, aspects and features are also disclosed.

摘要： In a system for analyzing samples by mass spectrometry, analyte ions are analyzed first by field asymmetric ion mobility spectrometry (FAIMS) before being analyzed by a mass analyzer. The analyte ions are produced in an ion source operating at near atmospheric pressure and transferred via a dielectric capillary into the vacuum system of the mass analyzer. While passing through the capillary, the ions are analyzed by FAIMS via electrodes on the interior wall of the capillary.

摘要： Ion mobility spectrometer. The spectrometer includes an enclosure for receiving a sample therewithin and an electron beam window admits an electron beam into the enclosure to ionize the sample in an ionization region. A shutter grid is spaced apart from the ionization region and means are provided for sample ion preconcentration upstream of the shutter grid. The ion preconcentration is effective to reduce space charge resulting in a lowered threshold detection level.

摘要： A method is provided of operating a mass spectrometer apparatus comprising a pair of quadrupole rod sets. Each quadrupole rod set is operated in a mass resolving mode. They may be operated in the same or different stability regions. The rod sets are operated to select essentially ions of the same mass to charge ratio, and are operated such that the combined resolution of the two rod sets is greater than the resolution of either rod set. The rod sets can be operated at relatively low resolution, with the combined peak shape from the two rod sets showing high resolution. This can make up for mechanical imperfections in the rod sets, losses due to high gas pressures, etc. A mass shift can be provided to give the desired resolution. The rod sets can be close coupled, and for this purpose neutralizing capacitors can be provided to prevent electrical interference between adjacent rod sets. The rod sets can be provided with the same frequency signal, which preferably is a phase locked and shifted, to give enhanced sensitivity.

摘要： A method and apparatus for extracting for quantitative analysis ions of selected atomic components of a sample (14). A lens system (46, 50, 54) is configured to provide a slowly diminishing field region for a volume containing the selected atomic components, enabling accurate energy analysis of ions generated in the slowly diminishing field region. The lens system (46, 50, 54) also enables focusing on a sample (14) of a charged particle beam, such as an ion beam (18), along a path length perpendicular to the sample and extraction of the charged particles (88) along a path length also perpendicular to the sample (14). Improvement of signal to noise ratio is achieved by laser excitation of ions to selected autoionization states before carrying out quantitative analysis. Accurate energy analysis of energetic charged particles is assured by using a preselected resistive thick film configuration disposed on an insulator substrate for generating predetermined electric field boundary conditions to achieve for analysis the required field potential. The spectrometer also is applicable in the fields of SIMS, ISS and electron spectroscopy.

摘要： An isotope ratio mass spectrometer (100) has an ion source (15), a static field mass filter (120), a reaction cell (30) to induce a mass shift reaction, and a sector field mass analyser (41, 42, 43) for spatially separating ions from the reaction cell (30) according to their m/z. A detector platform (50) detects a plurality of different ion species separated by the sector field mass analyser. The static field mass filter (120) has a first Wien filter (220) that deflects ions away from a longitudinal symmetry axis of the spectrometer (100) in accordance with the ions' m/z, and a second Wien filter (230) that deflects ions back towards the longitudinal symmetry axis in accordance with the ions' m/z. An inverting (lens (240) is positioned along the longitudinal axis between the Wien filters (220, 230) to invert the direction of deflection of the ions from the first Wien filter (220). The static field mass filter (120) provides high transmission and improved spectrometer sensitivity. The first and second Wien filters (220, 230) permit simple tuning.
