    Abstract: A method (10) permits determining the temperature in a magnetic resonance check weighing system (24) of a sample in a container (22) on a production line at the time of magnetic resonance testing. Method (10) includes the steps of determining a time-temperature correction factor for the sample in the container (50), measuring the temperature of the composite sample and the container at a time other than the time of magnetic resonance testing (70), and applying the correction factor to the temperature of the composite sample and container at a time other than the time of magnetic resonance testing (80).

    Abstract: A method of determining the mass of a moving sample is described, in which the sample is moved at a controlled velocity through a mass interrogation zone and a temperature interrogation zone, which may be upstream or downstream from the mass interrogation zone. Using a magnetic resonance method, a first signal is generated as the sample passes through the mass interrogation zone, the first signal having a characteristic that varies with the mass of the sample and with the temperature of the sample. A beam of electromagnetic radiation of a terahertz frequency or a near-infrared wavelength is generated and directed through the temperature interrogation zone. As the sample moves through the temperature interrogation zone, the electromagnetic radiation reflected from or transmitted through the sample is detected, and from that detected electromagnetic radiation a second signal is generated that has a characteristic that varies with the temperature of the sample. The characteristic of the first signal is adjusted using the second signal to produce a temperature compensated characteristic, which is compared to a similar characteristic obtained from a similar sample of known mass to determine the mass of the sample.

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