Abstract
A system and method for measuring the amount of sugar in a sample including measuring a solution of the sugar using oscillating electromagnetic fields generated in the sample at least two radio frequencies at which the electromagnetic properties of the solution differ. There are detected characteristics of the oscillating electromagnetic fields generated in the sample at each radio frequency that are dependent on the electromagnetic properties of the solution. A measure of the amount of sugar is derived from those characteristics. By combining measurements at different radio frequencies, the effects of changes in the ion concentration can then be removed to give an unambiguous measure for the sugar.
