Abstract

The present invention consists of an RF source (1) generating RF waves at two frequencies or more. These are transmitted by an antenna (2), to a reception antenna (6), via a vessel (4) containing an aqueous solution. The reception antenna (6) is linked to a device (7) measuring the intensity of the received RF power at the various RF frequencies used. The RF intensities thus measured are compared, yielding the frequency dependence of the RF attenuation by the passage of the waves in the vessel. This frequency dependence is then compared to the RF attenuation frequency dependence, obtained by the same system on a set of reference solutions having known osmolalities, thus deriving the osmolality of the solution contained in said vessel.
