ESNR Electronic Sensor Technology Inc (CE)

Electronic Sensor Technology Inc. (PINKSHEETS: ESNR), a leading provider of ultra-fast vapor analyzers, announced today that it has received a contract from a major airline to characterize in flight cabin air.

The airline industry is always working to improve the public's flying experience. Under this contract, EST will work in conjunction with a major airline to develop a profile of odors normally found in airplane cabins in flight. In addition, EST will look for the presence of vapors that may be associated with aircraft systems such as air conditioning, hydraulic control systems, auxiliary power units, etc. The airline believes that by evaluating air quality on a regular basis, it will be able to better maintain both the passenger comfort systems and the safety systems, saving costs and improving aircraft utilization and increasing passenger comfort.

The zNOSE is a very versatile, ultra-fast Gas Chromatography instrument (GC). More than 600 instruments have been sold around the world. The instrument is used wherever real time analysis of volatile organic compounds and vapors is required. These include detection of contamination of drinking water supplies, detection of explosives narcotic contraband, food adulteration. It is used in medical research to detect trace amounts of volatile organic compounds found in human breath that are associated with lung cancer and other diseases.
