Method for identifying sample in container, involves disposing container with sample in form of resonator and high-frequency signal is injected into resonator for exciting resonant mode of resonator

摘要

The method involves disposing container with the sample in the form of a resonator (8). A high-frequency signal is injected into the resonator for exciting a resonant mode of the resonator. The resonant electric field of the resonator penetrates a part of the sample in the container and the resonance curve of resonant mode is measured with and without the sample. The sample container has label of glass or plastic or ceramic with or without partial metallization and the opening of the metallic housing is directed towards the sample container. An independent claim is also included for a device for executing the method.
