Latest Patents

Feng Hong holds 1 patent for his invention titled "Photoemissive Ion Mobility Spectrometry in Ambient Air." This patent describes a photoemissive ion mobility spectrometer that utilizes backside illumination of a thin gold film. By employing pulsed laser radiation or a pulsed ultraviolet xenon flashlamp, the device produces bursts of low-energy photo-emitted electrons. These electrons interact with electronegative analytes or reactant molecules, facilitating charge transfer to the analyte. The incorporation of total internal reflection using optical elements, such as a fused silica prism, further enhances the spectrometer's performance. This technology allows for the direct vaporization of adsorbed explosive molecules from surfaces, followed by their injection into the spectrometer through a heated inlet.
