摘要： Magnetic resonance methods are provided for determining the mass of samples in vials (1) in a production line, each sample having a net magnetisation capability, including the steps of applying a first magnetic field in a first direction in an interrogation zone (25) for creating a net magnetisation within a sample located within the interrogation zone (25), applying an alternating magnetic field in a second direction in the interrogation zone (25) for temporarily changing the net magnetisation of the sample located within the interrogation zone (25), monitoring energy emitted by the sample as the net magnetisation of the sample returns to its original state and generating an output signal whose current amplitude is proportional to the energy emitted, comparing the current amplitude with like data obtained from at least one similar sample of known mass, and determining the mass of the sample. The step of applying an alternating magnetic field includes the step of triggering application of the alternating magnetic field when the sample is located at a position (PM) within the interrogation zone (25) with the current amplitude at its maximum.

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).

摘要： Parameters of a freeze drying process are monitored by measuring trace materials in the vacuum pump exhaust. The measurements are made using techniques such as acousto-optic spectrometry, multipass cavity-enhanced absorption spectrometry (CEAS) and cavity ring-down spectrometry (CRDS). The technique may be used to diagnose problems such as leakage in the freeze drying shelves, leakage in the condensation coils, leaks from atmosphere in the chambers and the presence of residual cleaning materials. The technique may also be used to monitor the presence of water vapor in the exhaust of a secondary drying process.
