A chemical sensing system includes a substrate material, a detector capable of indicating a presence of a target compound, gas, or vapor, and a heater for rapidly releasing compounds, gases and vapors from the substrate material. The substrate material acts to concentrate the compounds, gases, and vapors from a sample area for improved detection by the detector.

Chemical sensing device

In an embodiment, an apparatus includes a module assembly and a main assembly. The module assembly includes a module assembly housing, a first faceplate and an analysis unit attached to the first faceplate. The main assembly includes a main assembly housing, a second faceplate and an engine unit rigidly attached to the second faceplate. The engine unit generates a light that passes to the analysis unit via a first lens assembly and a second lens assembly. The first lens assembly is attached to the first faceplate and the second lens assembly is attached to the second faceplate. The module assembly when attached to the main assembly causes the first and second faceplates to act as a single mechanical unit that moves independent of movement of the module assembly housing and/or the main assembly housing.

Modular vapor detector and identifier

An explosive detection system based on an ion mobility spectrometer detects the presence of trace molecules in air. Such instruments require an ion source to ionize the trace molecules. An ion source that does not require a radioactive source to operate can use the photoelectric effect to produce electrons. Such a photoelectric ion source will gradually be contaminated and lose its photoelectron emission properties when operated in the air. The photocathode of the ion source can be automatically regenerated by a heater in thermal communication with the photocathode. The heater may be activated when the photoelectron emission falls below a predetermined value ro may run or cycle continuously.

The presence of trace molecules in air may be determined using an ion mobility spectrometer. Such devices may be used in the fields of explosives detection, identification of narcotics, and in applications characterized by the presence of very low airborne concentrations of organic molecules of special interest. The sensitivity of such instruments is dependent on the method of gas sampling utilized. A cyclone sampling nozzle can greatly improve the sampling efficiency, particularly when the sampling needs to be performed at a distance from the air intake. The cyclone sampling nozzle consists of an intake gas flow and a separate coaxial emitted gas flow which is deflected to move with a circular motion.

An explosive detection system detects the presence of trace molecules in air. The sensitivity of such instruments is dependent on the concentration of target gas in the sample. The sampling efficiency can be greatly improved when the target object is warmed, even by only a few degrees. A directed emission of photons, typically infrared or visible light, can be used to significantly enhance vapor emission. The sensitivity of such instruments is also dependent on the method of gas sampling utilized. A cyclone sampling nozzle can greatly improve the sampling efficiency, particularly when the sampling needs to be performed at a distance from the air intake.
