Latest Patents

Kang-Chieh Fan 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, the first stage utilizes carbon brushes as discharge electrodes to charge aerosol particles. These particles are then collected on a cylinder wall by an electric field set up between a high-voltage central metal rod and a grounded cylinder in the second stage. In the wet mode, deionized (DI) water is injected into an electrostatic particle-into-liquid sampler (EPILS) in a pulsation manner. This process effectively dislodges aerosol particles deposited on the cylinder wall, transforming them into a liquid aerosol sample. The liquid aerosol sample is subsequently analyzed for chemical compositions automatically.
