| 520 | 3 | |a The Curie-Weiss law has been applied to develop a quantitative analytical method referred to as the "effective magnetic moment method” without the use of any reference material for determining the "amount of substance.” This nondestructive and non-separation analytical method was validated by using samples of gadolinium oxide (Gd2O3) mixed in silicon oxide. Prior to validation, the magnetic field strength, temperature, and magnetic moment [measured with a superconducting quantum interference device (SQUID) as magnetometer] were calibrated to improve the accuracy of results obtained by this analytical method, using a nuclear magnetic resonance probe magnetometer with a custom-made probe, a platinum resistance thermometer, and a standard reference material of known magnetic moment. For regression analysis of magnetic moment and temperature data, the values of three unknown parameters and their uncertainties were calculated by using a custom-made program based on the nonlinear least-squares method. In the validation results, the relative difference between the mass fractions of Gd2O3 in mixture samples obtained by this method and those obtained by gravimetric blending was approximately 2%, when the mass fraction of Gd2O3 ranged from 0.04kgkg−1 to 1kgkg−1 and the mass of the sample ranged from 17mg to 62mg. The uncertainty of the mass fraction was approximately 5%, as evaluated by this analytical method. A prevalent source of uncertainty in this method is the reproducibility of measured magnetic moments in the SQUID. | |
