| titleOfInvention | System and method for measuring ultrafine particles based on surface acoustic wave technology |
| abstract | The invention discloses a system and a method for measuring ultrafine particles based on a surface acoustic wave technology, wherein the measuring system comprises: the sample gas processing unit is used for heating, filtering and controlling the amount of sample gas, and specifically comprises a heater, a filter and a sample gas flow controller; the particle electrostatic ionization unit is used for ionizing and diluting ultrafine particles in the sample gas; the device specifically comprises an ionization chamber and a dilution chamber; the electrostatic deposition sampling unit is used for collecting ultrafine particles and collecting frequency signals of the surface acoustic wave sensor, and is also provided with an exhaust port and a pump for exhausting the ultrafine particles; and the control and operation unit is used for determining the mass of the ultrafine particles according to the electric signals and the flow. By adopting the system and the method for measuring the ultrafine particles based on the surface acoustic wave technology, the concentration of the ultrafine particles in the atmosphere can be measured finely, and repeated measurement can be realized. |
