摘要:
A device for separating micro particles is provided. The separating device comprises a sample inlet into which a sample containing micro particles is injected; fluid inlets into which fluid is injected to form a flow sheath for the sample; a plurality of outlets through which the micro particles are separated and discharged out; a channel through which the sample and the fluid flow; and a first electrode and a second electrode longitudinally disposed in parallel in the channel. The first and the second electrodes are provided in such a manner that an electrode gap between the first and the second electrodes has a curved shape. The micro particles in the sample are easily separated using a dielectrophoresis characteristic.

Disclosed are an apparatus and a method for detecting particles and microorganisms using a magnetic field. The apparatus comprises a magnetic sensor that is provided at an outside of a passage pipe and measures a magnetic field induced by fluid moving in the passage pipe; an electrode that is provided in the passage pipe so as to apply electric current having a predetermined frequency to the fluid moving in the passage pipe to measure impedance; and a signal processing unit that uses an intensity of the magnetic field measured by the magnetic sensor and the impedance measured by the electrode to determine concentrations of particles and microorganisms included in the fluid. According to an embodiment of the invention, using electrical properties of the particles or microorganisms, it is possible to quantitatively analyze and to identify the particles or microorganisms in real time, to improve a measuring accuracy and to manufacture an ultra small-scaled particle and microorganism detecting apparatus having a simple structure.
摘要:
An apparatus for detecting a microorganism or micro-particle in real time includes an electrical charging module which electrically charges a microorganism or micro-particle in an atmosphere, a collection module which collects the electrically charged microorganism or micro-particle by using a potential difference, a preprocessing module which applies a fluorescent material to the collected microorganism or micro-particle and a sensing module which irradiates a light, senses a microorganism or micro-particle which reacts to the light and detects a concentration of the microorganism or micro-particle in the atmosphere.
摘要:
An apparatus for detecting a microorganism or micro-particle in real time includes a collection module comprising a condensation element unit which condenses water particles in an atmosphere and forms a droplet to which a microorganism or micro-particle in the atmosphere adheres to, and a collection channel unit which gathers the droplet and generates a droplet stream and a sensing module including a counting module. The droplet stream is introduced to the sensing module, and the sensing module detects and counts the microorganism or micro-particle which is adhered to the introduced droplet stream.
