摘要： The present invention relates generally to a multi-reflecting time-of-flight mass spectrometer (MR TOF MS). To improve mass resolving power of a planar MR TOF MS, a spatially isochronous and curved interface may be used for ion transfer in and out of the MR TOF analyzer. One embodiment comprises a planar grid-free MR TOF MS with periodic lenses in the field-free space, a linear ion trap for converting ion flow into pulses and a C-shaped isochronous interface made of electrostatic sectors. The interface allows transferring ions around the edges and fringing fields of the ion mirrors without introducing significant time spread. The interface may also provide energy filtering of ion packets. The non-correlated turn-around time of ion trap converter may be reduced by using a delayed ion extraction from the ion trap and excessive ion energy is filtered in the curved interface.

摘要： A time of flight mass analyser 1 having a drift region 2, an ion packet generator 6, first and second ion reflectors 18,19 and at least one ion detector 20 is disclosed. The drift region 2 has an axis 3, an entrance 4 and an exit 5 and provides for a place wherein ions may be temporally separated according to their mass-to-charge ratios. The ion packet generator 6 injects packets of ions into the drift region 2 at the region's entrance 4 from a beam of ions by intermittently applying an electrostatic field such that the packets of ions enter the drift region 2 in an initial direction which is inclined to the direction of said beam of ions. The first ion reflector 18 is disposed at the exit 5 of the drift region 2 to reflect back towards the entrance 4 ions which are travelling towards the reflector 18 in the drift region 2. The second ion reflector 19 is disposed in juxtaposition to the first ion reflector 18 to reflect packets of ions back towards the first ion reflector 18 through at least a portion of the drift region 2 so that the packet of ions may be reflected to and fro between said first 18 and second 19 ion reflectors and undergo a number n of reflections at the second ion reflector 19. A detector 20 is disposed to detect at least some packets of ions reflected by the first ion reflector 18 which do not enter the second ion reflector 19. The number of reflections at the second ion reflector 19 may be selected by adjustment of an inclination of the initial direction to the axis 3.

摘要： This invention relates to the analytical electronics used to identify compositions and structures of substances, in particular, to the analyzers comprising at least one mass-spectrometer (MS) and may be applied in such fields as medicine, biology, gas and oil industry, metallurgy, energy, geochemistry, hydrology, ecology.
Technical result provides the increase in MS resolution capacity, gain in sensitivity, precision and measurement rates of substances compositions and structures concurrently with enhancement of analyzer functional capabilities, downsizing and mass reduction.
A multipath method of mass-spectrometry and a three-dimensional reflecting (-reflecting) method of mass-spectrometry requiring to use a three-dimensional reflecting IO sub-system (- reflector) are developed. A new type of electric field distribution such as transversely discontinuous conic field distribution, including its type of three-dimensional distribution in area of reflection, is proposed to implementing said methods.
Versions of devices to implement the claimed method are developed.
Proposed schematic ion optical diagrams allow to developing different MS types.

摘要： A charged particle trap for trapping of a plurality of charged particles, and a method of operating said trap. The trap includes first and second electrode mirrors (2,3) having a common optical axis (4), the mirrors being arranged in alignment at two extremities thereof. The mirrors are capable, when voltage is applied thereto, of creating respective electric fields defined by key field parameters. The electric fields are configured to reflect charged particles causing their oscillation between the mirrors. The method includes introducing into the trap, along the optical axis, the plurality of charged particles as a beam (10) having pre-determined key beam parameters. The method further includes choosing the key field parameters for at least one of the mirrors such as to induce bunching among charged particles in the beam.
