Method for analysing the dielectric polarisation of anaesthetic agents and an analyser

摘要

A method for analysing anaesthetic agents (16) is described. In the method a parameter directly related to the anaesthetic agent's (16) dielectric polarisation is determined in order to analyse the anaesthetic agent (16). This method can be performed with an analyser according to the invention. The analyser comprises a measuring unit with a container (14) for the substance (16), two capacitor plates (18), devised so a substance can be interposed between them for analysis, a voltage source (20), connectable to the capacitor plates for controlled application of at least one voltage (10) across same, and a voltmeter (24), connectable to the capacitor plates (18) for measuring a voltage (12) across the capacitor plates (18). An analysis unit (28) then analyses the anaesthetic agent (16).
