Patent number: 12292399Abstract: The capabilities of a gas or liquid chromatography-molecular rotational resonance (GC/LC-MRR) instrument exceed those of high-resolution mass spectrometry and nuclear magnetic resonance in terms of selectivity, resolution, and compound identification. MRR detection provides high specificity for selective gas- or liquid-phase separations, including the ability to resolve co-eluting peaks and isomeric compounds without any loss of specificity or accuracy. MRR can perform both qualitative identification and absolute quantification of analyte components separated by GC or LC without a reference standard. GC-MRR is ideal for compound-specific isotope analysis (CSIA) and can identify enantiomers and enantiomeric excess. GC-MRR measurements are especially useful for studying biosynthetic/degradation and geochemical isotopic compounds.Type: GrantFiled: May 7, 2020Date of Patent: May 6, 2025Assignee: BrightSpec, Inc.Inventors: Justin L. Neill, Matt Muckle, Alexander V. Mikhonin, Walter H. Colsman, Daniel W. Armstrong

Patent number: 12288131Abstract: Fermions are the building blocks of matter. Here, we disclose a robust quantum register composed of hundreds of fermionic atom pairs trapped in an optical lattice. With each fermion pair forming a spin-singlet, the qubit is realized as a set of near-degenerate, symmetry-protected two-particle wavefunctions describing common and relative motion. Degeneracy is lifted by the atomic recoil energy, which depends on mass and lattice wavelength, thereby rendering two-fermion motional qubits insensitive to noise of the confining potential. The quantum coherence can last longer than ten seconds. Universal control is provided by modulating interactions between the atoms. Via state-dependent, coherent conversion of free atom pairs into tightly bound molecules, we tune the speed of motional entanglement over three orders of magnitude, yielding 104 Ramsey oscillations within the coherence time.Type: GrantFiled: June 24, 2021Date of Patent: April 29, 2025Assignee: Massachusetts Institute of TechnologyInventors: Martin Zwierlein, Thomas Richard Hartke, Ningyuan Jia, Botond Oreg

Patent number: 12283460Abstract: A system and method for creating a beam current profile that eliminates variations that are not position dependent is disclosed. The system includes two Faraday sensors; one which is moved across the ion beam and a second that remains at or near a certain location. The reference Faraday sensor is used to measure temporal variations in the beam current, while the movable Faraday sensor measures both the position dependent variations and the temporal variations. By combining these measurements, the actual position dependent variations of the scanned ion beam can be determined. This resultant beam current profile can then be used to control the scan speed of the electrostatic or magnetic scanner.Type: GrantFiled: August 29, 2022Date of Patent: April 22, 2025Assignee: Applied Materials, Inc.Inventors: Tyler Wills, Richard Allen Sprenkle

Patent number: 12283474Abstract: Systems and methods are disclosed for dynamically switching an ion guide and a TOF mass analyzer between concentrating or not concentrating ions in a targeted acquisition. Product ions are ejected from the ion guide into the TOF mass analyzer and the intensity of a known product ion is measured at two or more time steps. The ion guide initially ejects product ions using a sequential or Zeno pulsing mode that concentrates product ions with different m/z values within the TOF mass analyzer at the same time. If the intensity of the product ion is increasing and greater than a threshold intensity, the ion guide switches to a continuous or normal pulsing mode that does not concentrate ions with different m/z values in the TOF mass analyzer at the same time. Similarly, if the intensity decreases below a threshold in continuous mode, the ion guide switches back to sequential mode.Type: GrantFiled: April 10, 2019Date of Patent: April 22, 2025Assignee: DH TECHNOLOGIES DEVELOPMENT PTE.
