Apparatus and method for analysing fluids

摘要

Apparatus for analysing fluids, especially body fluids and blood, includes means for applying an oscillating electric field 1 to a sample of fluid and means for measuring electrical current flowing in the sample being analysed as a result of application of the applied field to enable the loss factor of an electrical circuit in which the sample is comprised to be determined. Changes in the loss factor with the frequency of field applied can be determined and by comparison with stored data, used to identify the presence and concentration of substances in a fluid. The apparatus may be arranged to analyse blood in a living body.
