Snohomish Sheriff's Office Selects zNose for Contraband Applications

June 26, 2006

Electronic Sensor Technology's electronic nose chosen by Washington state law enforcement agency for detection of conventional and plastic explosives and drugs.


NEWBURY PARK, Calif. /BUSINESS WIRE/ -- Electronic Sensor Technology (EST), a leading provider of innovative homeland security and environmental solutions, announced that the Sheriff's office of Snohomish County in Washington has selected zNose of Electronic Sensor Technology (EST) for contraband applications.

EST's staff was at the Sheriff's Office, training a group of officers in the operation of zNose for detecting conventional and plastic explosives and also drugs of abuse. Samples of explosives and drugs were demonstrated, and the officers were pleased that zNose could complement the dogs in quantifying the detected substances.

Unlike conventional trace detection systems, which can only detect a small number of specific chemical elements, the zNose is a true electronic nose, designed to recognize the unique chemical fingerprint or olfactory signature of any odor, fragrance, or vapor, and it can adaptively be trained to recognize the chemical profile of any terrorist threat. The zNose is unique because it can also create an unlimited number of virtual chemical sensors for trace detection while at the same time recognizing chemical profiles associated with conventional and nonconventional terrorist threats.

Further details on the use of zNose for contraband is available through the following link: click here.
