A novel device called the Bioscope System is investigated for feasibility as sensor for chemicals in aqueous solutions. Thereby a sample is examined by a pulsed voltage and electrical properties of that sample are measured. These electrical properties can be considered as a sum parameter of the sample in terms of conductivity and permittivity. It is demonstrated that the Bioscope System can indeed measure differences between different substances in aqueous solution and between different concentrations of the same substance in aqueous solution. A qualitative explanation is provided. Possible improvements of the system are suggested.
