Nuclear Magnetic Resonance (NMR) Experimental Apparatus

BEX-8505
Nuclear Magnetic Resonance (NMR) Experimental Apparatus

The Nuclear Magnetic Resonance (NMR) experiment is a fundamental component of modern physics laboratory courses in universities for science and engineering students. It has an open design for direct observation of key components like the detection coil, sweep coil, excitation coil, and sample position within the magnetic field. Paired with a user-provided oscilloscope, it allows observation of the NMR phenomenon through the field sweep method and measurement of resonance frequencies, making it suitable for foundational modern physics experiments in higher education.

Features of BEX-8505 Nuclear Magnetic Resonance (NMR) Experimental Apparatus

  • Interchangeable Samples: Supports free replacement of experimental samples. In addition to the provided samples, users can conduct measurements with their own prepared samples.

  • Tunable Electromagnet: Utilizes an electromagnet to provide the main magnetic field, allowing free adjustment of the field strength. Compared to permanent magnets, this enables the measurement of multiple data sets at different field strengths, increasing experimental scope and enhancing the accuracy of results.

  • Adjustable Sample Position: Components are secured using an optical rail and adjustable poster, enabling two-dimensional positioning of elements within the magnetic field.

  • Convenient Field Measurement: Includes a Teslameter probe clamp for convenient magnetic field measurement.

  • Open Structure: The open design facilitates intuitive observation of the detection coil, sweep coil, excitation coil, and the sample's role and position within the field.

  • Flexible Data Acquisition: Resonance signals can be acquired and displayed using an optional oscilloscope or an optional PASCO digital science experimental interface.

Applications of BEX-8505 Nuclear Magnetic Resonance (NMR) Experimental Apparatus

  • Observe the NMR phenomenon for hydrogen nuclei in liquid samples and fluorine nuclei in solid samples.

  • Calculate the g-factors for hydrogen and fluorine nuclei.
