    • Disclosed herein is an apparatus and method for detecting the motion characteristics of particles in a flow channel. The apparatus of the present invention includes first and second electrode groups, each comprising a pair of electrodes, which are arranged to be spaced apart from each other in a flow channel, the pair of electrodes functioning as both a drive electrode and a sensing electrode for directly applying voltage and measuring impedance between the electrodes. An operation control unit measures variation in electrical pulses generated in the first and second electrode groups, thus detecting motion characteristics of the particles. The present invention is advantageous in that it does not require complicated optical measuring instruments or analyzing instruments, and in that it can be used to easily detect the motion characteristics of particles in a flow channel merely by analyzing variation in electrical pulses without requiring preliminary information.

    • Disclosed is a device for measuring the concentration of fine particles contained in a fluid. The device comprises a control volume body (10) having a predetermined effective volume. An inlet path (20) is formed at an end of the control volume body to feed the fluid into the control volume body therethrough. An outlet path (30) is formed at another end of the control volume body to discharge the fluid from the control volume body therethrough. Measuring instruments (40) are provided at the inlet path and the outlet path to emit electrical signals when the fine particles pass through the inlet path and the outlet path. A computing machine (50) receives the electrical signals transmitted from the measuring instruments, and then computes the number and the concentration of fine particles contained in the control volume body. The device is easily integrated with Micro-TAS (Total Analysis System).
