摘要： Magnetic resonance measurement methods for determining the mass of samples are provided in which magnetic field homogeneity is determined, compensation is provided for potential drifts in the measuring system, and the presence of metal in samples is determined. The methods include applying a magnetic field in a first direction in an interrogation zone for creating a net magnetisation within a sample located within the interrogation zone; applying an alternating magnetic field in a second direction in the interrogation zone for temporarily changing the net magnetisation of the sample located within the interrogation zone; monitoring energy emitted by the sample as the net magnetisation of the sample returns to its original state and generating an output signal having a characteristic which is proportional to the energy emitted; and comparing the output signal of the monitoring with other data.

摘要： A radio frequency (RF) probe (10) for a nuclear magnetic resonance check weighing system produces a uniform magnetic field at the center of RF probe (10), has minimal sensitivity to electrical interference from external sources, shapes the magnetic field to minimize cross coupling from packages such as drug vials (22) not under test, and presents minimal airflow obstruction. RF probe (10) includes a coil (100) with a plurality of conductive loops (102, 104) having a rectangular cross section carried inside two opposing, rectangular cross section housings (106, 108), respectively. Housings (106, 108) are spaced apart and in parallel, creating an “open probe” configuration permitting a conveyor belt (28) carrying vials (22) whose contents are to be checked to pass between housings (106, 108), and allows airflow surrounding the vials (22) and conveyor belt (28) to pass substantially without obstruction. Conductive loops (102, 104) and the housings (106, 108) carrying them may be placed such that the longitudinal axis of coil (100) is oriented in either horizontal or vertical spatial relation with conveyor belt (28).
