Abstract
In a method for analyzing anaesthetic agents and an analyzer operating according to the method, a parameter directly related to the anaesthetic agent's dielectric polarization is determined. A measuring unit has a container for the anaesthetic agent, two capacitor plates, devised so the anaesthetic agent can be interposed between them for analysis, a voltage source, connectable to the capacitor plates for controlled application of at least one voltage across the plates, and a voltmeter, connectable to the capacitor plates for measuring a voltage across the capacitor plates. The measurement results are analyzed in an analysis unit and the anaesthetic agent is identified from the analysis result. Mixing and/or contamination of anaesthetic agents can also be identified.
