ESNR Electronic Sensor Technology Inc (CE)

Electronic Sensor Technology (OTCBB: ESNR) a leading provider of ultra-fast vapor analyzers, announced today that its zNose® electronic sensor instrument can detect tribromoanisole TBA and trichloroanisole TCA.

TBA is an anti-sap-staining chemical used on wood in South America, primarily from Chile and Brazil. It was the chemical contaminant cited in the recent consumer product recall as causing nausea, vomiting, diarrhea and stomach pain in at least 70 consumers, according to the FDA.

TCA is responsible for "cork taint" a contamination of wine that leaves it with a musty moldy taste, and smelling like wet dog.

The chemicals are suspected of causing nausea, vomiting and diarrhea.

EST's zNose® electronic sensor instrument is able to capture and analyze nearly any odor, fragrance or chemical vapor within ten seconds, and can detect TCA and TBA in woods. Moisture is responsible for the possible growth of molds and toxic substances which produce musty smells.

The following is a technical paper which describes the use of zNose® for detecting TBA and TCA

The zNose® is a very versatile, ultra-fast Gas Chromatograph (GC). It can perform a full hydrocarbon analysis. This episode demonstrates one of the many zNose®'s applications. It is currently being used for environmental, food/beverage, petro-chemical, life science and Homeland Security applications. For more information, please visit our website at www.estcal.com
