Sample e.g. acetone, identifying method, involves measuring resonance curve of resonant mode with and without sample, and identifying sample based on determined variation of resonance frequency compared to measurement without sample

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a method and device for identifying a chemical sample (such as acetone) by measuring how the sample affects the resonance frequency of a resonator. A high-frequency signal excites the resonator, and differences in resonance curves (with and without the sample present) are analyzed to determine the sample's identity.

Patent Abstract

The method involves disposing a container with a sample is disposed in a form of a resonator (8), and injecting a high-frequency signal into the resonator for exciting a resonant mode of the resonator. A part of the sample in the container is penetrated by resonant electric field of the resonator. A resonance curve of the resonant mode is measured with and without the sample. The sample is identified based on a determined variation of resonance frequency compared to the measurement without sample. An independent claim is also included for a device for identifying a sample in a container.
