Analytical compound separating and analytic substance detection, involves subjecting electrodes with uniform alternating voltage signal, measuring voltage and/or current values in electrodes to determine conductivity values

摘要

The process involves measuring conductivity in a contactless manner in a separation chamber using electrodes (15, 16) for detection of an analytic substance. The electrodes are subjected to a uniform alternating voltage signal or alternating voltage signals of different frequencies. The voltage and/or current values are measured in the electrodes at a number of points and conductivity values are determined from the values. An independent claim is also included for a device for separating an analytic compound and for detecting an analytic substance.
