Latest Patents

Ivan Boldin holds a patent for "Ion cyclotron resonance measuring cells with harmonic trapping potential." This invention encompasses devices and methods for acquiring mass spectra with very high mass resolution in ion cyclotron resonance mass spectrometers. The design features cylindrical ICR measuring cells with specialized electrode geometries that generate harmonic trapping potentials for orbiting ions. The sheath of the cylindrical cell is divided by longitudinal gaps into multiple sheath electrodes, which can either carry layers with resistance profiles to create parabolic voltage profiles or form sheath electrodes of varying widths through parabolic gaps. This innovative design allows orbiting ions of a specific mass to oscillate harmonically in an axial direction at a consistent frequency, regardless of their orbit radius or oscillation amplitude. The cylinders are ideally capped with rotationally hyperbolic endcaps, divided into partial electrodes, and the ions are excited by dipolar excitation fields. This advancement enables ion clouds to be maintained for significantly longer periods than previously possible.
