| titleOfInvention | Method and system for analyzing neodymium isotope in rare earth-rich neodymium element mineral |
| abstract | The invention belongs to the technical field of all-rock neodymium isotope testing, and discloses a method and a system for analyzing neodymium isotopes in rare earth-rich neodymium element minerals, wherein an instrument which is combined by a laser ablation system and an inductively coupled plasma mass spectrometer is used for collecting signals with the mass numbers of 142,143,144,145,146,147 and 149 in a standard sample and an unknown sample; of Sm in the sample 144 Sm isotope pair 144 Interference of Nd 147 And subtracting the Sm signal and the isotope natural abundance of the element Sm, and correcting the element fractionation effect and the mass discrimination effect by adopting an external standard method. The invention shortens the debugging time of the instrument, improves the experimental efficiency, and compiles data processing software 'Nada' for batch calculation, abnormal screening, peak filtering and data result formatting; and performing neodymium isotope tests in sequence, wherein the result is consistent with the recommended value within the error range. |
