摘要：
An exemplary embodiment of this invention relates to a method of inspection of a filled hard capsule sealed with a solvent sealing agent, including a process for determining the quality of the seal. The process may include: supplying a filled hard capsule sealed with a solvent sealing agent supplying a microwave resonator wherein a measuring field having a resonance curve is generated directing the capsule through the measuring field measuring characteristics related to the modification of the resonance curve produced by the presence of the capsule in the measuring field, in comparison with a reference resonance curve corresponding to an empty state of the resonator and using the measured characteristics to determine a value associated with the quality of the seal. Other exemplary embodiments of this invention relates to a method for sorting capsules on the basis of the result of the inspection method and to an associated equipment able to carry out such methods.
