Nuclear Magnetic Resonance (NMR) is a powerful analytical technique used to determine the moisture content of metals. It is a non-destructive method that can be used on a wide variety of metals, including aluminum, steel, and copper. NMR is based on the principle that the nuclei of certain atoms, such as hydrogen, have a magnetic moment. When these nuclei are placed in a magnetic field, they align themselves with the field. The energy required to align the nuclei is dependent on the strength of the magnetic field and the type of atom. By measuring the energy required to align the nuclei, it is possible to determine the moisture content of the metal.
NMR moisture analysis is a relatively simple process. The metal sample is placed in a sample holder and inserted into the NMR spectrometer. The spectrometer generates a magnetic field and measures the energy required to align the nuclei of the hydrogen atoms in the metal. The moisture content of the metal is then calculated based on the energy measurement.
NMR moisture analysis is used in a variety of applications, including:
