Latest Patents

Yu-Shan Yang holds a patent for a semi-dry type method for automatically sampling PM2.5 particles. This method collects aerosol samples in a dry mode and extracts them in a wet mode to prevent sampling artifacts. In the dry mode, carbon brushes are utilized as discharge electrodes to charge aerosol particles, which are then collected on a cylinder wall by an electric field. The wet mode involves injecting deionized water into an electrostatic particle-into-liquid sampler in a pulsation manner, effectively dislodging aerosol particles to create a liquid aerosol sample for chemical analysis.
