Latest Patents

Siqin He holds a patent for an "Electrospray ionizer for mass spectrometry of aerosol particles." This device and method enable the application of ESI-based mass spectroscopy to submicrometer and nanometer scale aerosol particles. The technology utilizes unipolar ionization to charge the particles, allowing for their electrostatic collection on a tungsten rod. The collected particles are then dissolved by a liquid flowing over the tungsten rod, forming highly charged droplets that release unfragmented ions for mass spectroscopy, such as time-of-flight mass spectroscopy. The device is designed to operate in a switching mode, facilitating aerosol deposition while solvent delivery is turned off and vice versa.
