Moisture content determination is a critical analytical measurement in various industries. Magnetic resonance methods have emerged as powerful tools for non-destructive moisture analysis, providing precise and reliable data.

Nuclear Magnetic Resonance (NMR)

• NMR utilizes the magnetic properties of hydrogen atoms present in water molecules.
• A sample is placed in a magnetic field, causing hydrogen nuclei to resonate at specific frequencies.
• The intensity of the resonance signal is directly proportional to the amount of water present.
• NMR provides accurate moisture content measurements, especially for solid and semi-solid samples.

Magnetic Resonance Imaging (MRI)

• MRI is an advanced imaging technique that employs magnetic fields and radio waves.
• It generates detailed images of the sample, revealing the distribution of water and other components within.
• MRI allows for non-invasive moisture analysis in complex materials, such as food products and composites.
• The ability to visualize moisture distribution enables targeted sampling and further analysis.

Pros of Magnetic Resonance Methods

• Non-destructive: Samples remain intact after analysis, allowing for further testing or reuse.
• Accurate and precise: MRI and NMR provide quantitative and reliable moisture content measurements.
• Versatile: These methods are applicable to various sample types, including solids, liquids, and semi-solids.

Applications of Magnetic Resonance Methods

• Quality control in food, pharmaceutical, and chemical industries
• Material characterization and testing in construction and manufacturing
• Moisture monitoring in agricultural products, soil, and groundwater
