5. www.estcal.com Electronic Sensor Technology, Inc. Detects the unique chemical fingerprint or olfactory signature of any odor, fragrance, or vapor It can also create an unlimited number of virtual chemical sensors Can be adaptively trained to recognize the chemical profile of almost any terrorist threat 3 ways in which EST zNose® can help

6. www.estcal.com Electronic Sensor Technology, Inc. 4 Use-Cases for EST zNose® Screening of Cargo Containers Monitoring Ambient Air in the Government Buildings Monitoring Ambient Air in Subways Profiling Ambient Air in Commercial Airlines

7. www.estcal.com Electronic Sensor Technology, Inc. 100+ cargo ports in US 6 million+ cargo containers arrive at US ports every year Only 2% of containers were screened for threats before 9/11 Only 4% of containers are now screened post 9/11 So, it’s not a major improvement in the present dangerous situations, yet testing every container remains an elusive goal. Screening of Cargo Containers

8. www.estcal.com Electronic Sensor Technology, Inc. Presence of odoriferous chemicals such as trichlorophenol and trichloroanisole, which can damage or taint sensitive cargo Virtual sensor arrays and recognizable olfactory images can be used to detect and identify explosives, hazardous substances, drugs of abuse A cost effective and easy to use screening tool for shippers and inspectors alike Container security protocols specific odor profiles can also be attached to an electronic manifest file and forwarded to authorities Important note : The containers can be inspected through ventilation ports without having to open the containers, before the ship docks at the port. 5 ways in which EST zNose® can help

9. www.estcal.com Electronic Sensor Technology, Inc. A key challenge for Homeland security is eliminating key vulnerabilities in public buildings 3 ways in which EST zNose® can help – Monitor the ambient air within buildings Recognize known vapor threats, such as Nerve, blood or vomiting agents and detect suspicious odors, which are not part of the buildings normal vapor signature By monitoring the air chemistry within buildings and comparing it with the building’s normal background signature, new or suspicious vapors can be quickly identified and investigated. Monitoring Ambient Air in the Government Buildings
