摘要
A method and apparatus for identifying a sample in a container, provide for the container with the sample being disposed relative to a resonator, a high-frequency signal being coupled into the resonator for exciting a resonant mode of the resonator, the resonant electric field of the resonator penetrating part of the sample in the container, the resonance curve of at least one resonant mode being measured with and without the sample, and the sample being identified based on the determined change in the resonance frequency compared to a measurement without sample.
