APPARATUS AND METHOD FOR DETECTING PARTICLE AND MICROORGANISM WITH MAGNETIC FLUX

摘要

An apparatus and a method for detecting micro-particles and microorganisms using a magnetic field are provided to identify the micro-particles or the microorganisms in real time by using electrical characteristics of the micro-particles or the microorganisms. An apparatus for detecting micro-particles and microorganisms using a magnetic field includes magnetic sensors(211,212), electrodes(221,22,223,224), and a signal processor(250). The magnetic sensors are located outside a flow pipe(203) and measure a magnetic field induced by a fluid flowing in the flow pipe. The electrodes apply a current to the fluid to measure impedance. The signal processor determines concentrations of micro-particles and microorganisms included in the fluid by using the intensity of the magnetic field and the impedance.
