20120301361 | PORTABLE CHEMICAL DETECTOR - A portable chemical detector, an embodiment including a material that contains a dye and is permeable to one or more chemicals that activate the dye, a light emitter to transmit light through the material and dye, a light detector to detect the light and a housing in which the material containing the dye, the light emitter, and the light detector are disposed. | 11-29-2012 |
20120118144 | Vacuum Chromatography Gas Detector - A portable gas chromatography system and method of use. The portable gas chromatograph may be used to accurately and rapidly detect low-level concentrations of chemicals, such as fixed gases, volatilized liquid samples, or toxic chemicals and transmit to a user data relating to the presence and identity of such. The portable gas chromatograph uses an onboard vacuum source to pull samples into and through the system and thus does not require the use of a carrier gas. Further, the system comprises a solenoid valve for capturing the sample and may include a short porous layer open tubular separation column, and a thermal conductivity detector. Overall size and weight of the system is small enough for a user to carry. The method of operation of the gas chromatograph includes taking rapid successive samples and analyzing the data outputs using Fourier transform techniques. Such analysis allows real-time data updates and rapid detection of hazardous environmental agents. | 05-17-2012 |
