RASER and/or NMR Spectroscopy Device, Use of Such a Device, System with Two Such Devices, and Method for Operating Such a Device and Such a System

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel RASER and/or NMR spectroscopy apparatus incorporating an actively electronically damped resonant circuit. The invention uniquely uses an active electronic component—such as a negative impedance converter (NIC) or similar circuitry—to reduce electrical losses in the resonator, thereby significantly increasing its quality factor (Q). This results in a drastically higher signal-to-noise ratio and lowers the threshold for RASER (Radiofrequency Amplification by Stimulated Emission of Radiation) activity. The system can include two such devices—a main and a reference unit—for highly precise structure determination of molecules, improved magnetic field sensing, and compensation of environmental noise.

Use CasesContent extracted from patent full text and abstract with AI.

• Ultra-high precision NMR spectroscopy for determination of molecular and atomic structures, even for trace compounds or rare spins.
• Magnetometry—serving as a highly sensitive and precise magnetometer for scientific, industrial, or biomedical applications.
• Real-time monitoring of chemical reactions (reaction monitoring), including metabolic studies or pharmaceuticals research.
• Material detection and analysis in quality control or forensic applications.
• Compensation of magnetic field fluctuations in portable or less expensive NMR setups, making high-resolution spectroscopy more accessible.
• Measurement of rare or weak NMR signals that are not detectable with standard equipment.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increased signal-to-noise ratio (SNR) thanks to active damping and a drastically higher resonator quality factor.
• Lower threshold for RASER activity, enabling detection and analysis of molecules or nuclei with very small signals or low concentration.
• Possibility to use less expensive, less stable magnets (even portable ones) without compromising frequency precision, since environmental fluctuations are compensated.
• Simultaneous measurement and real-time correction using a reference device, thus removing field drift and environmental noise from main measurements.
• Extended measurement times allow for sub-millihertz (and potentially even microhertz) spectral resolution, far surpassing standard NMR devices.
• Practical detection of rare nuclei (e.g., 15N, 103Rh, 57Fe) that are inaccessible with conventional NMR, expanding research possibilities.
