Patent ID: 8330958

Claim:
A chemical detector for detecting various chemical compounds and comprising: a sensory element constructed of an organic-inorganic emissive nanocomposite, wherein nanocomposite includes nanoporous periodical semiconducting structure with alternating layers of high and low porosity infiltrated with sensory emissive organics; a flow channel with a pocket incorporating a sensory element; a flow cell for air pumping through a flow channel and air passing over a sensory element; a first optical fiber to excite luminescence of a sensory element and a second fiber to collect luminescence of a sensory element; a miniature spectrometer to analyze an intensity change and spectral shift of narrow luminescence peak upon exposure of analyte containing in the pumping air, processing algorithm to identify and quantify analytes in pumping air; a sampling system functioning in real-time mode to desorb particulates either evaporate them from inspected surface following analytes delivery and multiple cycling over a sensory element.
