摘要： Ion guides for use in mass spectrometry (MS) systems are described. The ion guides are configured to provide a reflective electrodynamic field and a direct current (DC or static) electric field to provide ion beams that are more spatially confined with a comparatively large mass range.

摘要： A mass analyzer comprises a pair of planar electrode structures. The electrode structures are disposed opposite one another, parallel to one another, and axially offset from one another. One of the pair of planar electrodes comprises an opening. The mass analyzer comprises an ion mirror disposed between the pair of planar electrodes. A mass spectrometer and a mass spectrometry method are also described.

摘要： The mass spectrometer includes a mass analyzer having a pair of planar electrode structures. The electrode structures are disposed opposite one another, parallel to one another, and axially offset from one another, and are structured to generate, in response to a common pattern of voltages applied to them, a cylindrically-symmetric, annular electric field surrounding a cylindrical central region. The electric field includes an annular axially focusing lens region surrounding the central region, and an annular mirror region surrounding the lens region. Ions injected tangentially in the central region towards the electric field reach an ion detector after executing a number of ellipse-like orbits, which enables a long flight path to be accommodated within a small evacuated space.

摘要： A mass analyzer comprises a pair of planar electrode structures. The electrode structures are disposed opposite to each other, parallel to each other, and axially offset from each other. The electrode structures are configured to generate, in response to an applied voltage, a cylindrically-symmetric, annular electric field comprising an annular radially focusing central lens region surrounding an axis of symmetry, and an annular mirror region surrounding the annular radially focusing central lens region.
