Latest Patents

One of his latest patents is a "Spectroscopic method and apparatus." This invention involves a method and apparatus for determining the concentration of a substance of interest using gas-coupled photoacoustic spectroscopy (GC-PAS). The method utilizes an essentially monochromatic beam of radiation in the optical portion of the electromagnetic spectrum, which is absorbed by the substance of interest. The beam is modulated at a sonic frequency to generate a primary signal that depends on the absorption coefficient of the substance. Additionally, a secondary signal is generated to compensate for operating parameters, allowing for a more accurate determination of the concentration of the substance.

Another significant patent is the "Photoacoustic analyzer and method." This invention describes a photoacoustic device designed for fluid analysis. The device consists of a source of a pulsating beam of light and an enclosure that holds at least one reference chamber and one measuring chamber. The design ensures that the light beam passes through the reference chamber before entering the measuring chamber, enhancing the accuracy of the analysis.
