Device for Generating and Detecting a Magnetic Resonance of a Sample

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

This invention describes a device for generating and detecting magnetic resonance in a sample using a novel assembly of at least two frequency-synchronized LC oscillators. Unlike traditional spectrometer equipment, this assembly can act simultaneously as both transmitter and receiver of magnetic resonance signals, thus enabling the excitation and detection of sample magnetization within a simplified, compact structure. The design facilitates high sensitivity for detecting electron or nuclear magnetic resonance, and supports both constant wave and pulsed experiments. The modular, integrated approach allows for enhanced miniaturization, reduced energy consumption, and cost-effective production, making the system adaptable for various analytical and imaging applications.

Patent Abstract

The invention relates to a device for generating and detecting a magnetization of a sample (103). The device at least comprises means (101) for providing a static magnetic field (102) of a predetermined direction and with a predetermined intensity at a sample location, a transmission device (104) for providing an additional magnetic field at the sample location and a receiving device (104) for detecting the magnetization of the sample (103). According to the invention, an assembly of at least two LC oscillators (104), the oscillation frequency of which being dependent on the value of an inductive element of the LC oscillators and which are frequency-synchronized by interconnection, can be used both as a transmission device (104) and as a receiving device (104) and also simultaneously as a transceiver (104). Means are connected for controlling the assembly (104), the assembly and control means (104) being sufficient to generate a magnetic field which is capable of deflecting a magnetization of the sample (103) out of equilibrium, and the sample location is situated in the near field of the assembly (104). In order to process an output voltage (105) of the assembly (104), demodulation means (106), analog to digital converters and means for digital data processing (107) are connected downstream of the device in a predetermined order. Provided on the means for digital data processing (107) are: means for determining the magnetization of the sample and the spin concentration of individual spectral components to be determined from said magnetization; and means for outputting said magnetization.
