5 key concerns of Homeland Security

The Government sponsored Homeland Security is facing 5 key concerns.

Terrorist Threats Maritime ports vulnerability Airport Security

Public Buildings Security Security in Public

Transportation Facilities






The Need of the Hour!

A sensor technology that can quickly adapt and recognize conventional and non-conventional threats.






Introducing…

Electronic Sensor Technology’s patented gas chromatographer

zNose ®

• 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

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






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






• 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.

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






800+ miles of US light Rail Network

1000+ stations in the US light Rail network

2800 million+ Daily Ridership on US Light Rail Transit

With most of the system underground it is vulnerable to Chemical attacks by Terrorists

Monitoring Ambient Air in Subways






• Eliminate vulnerabilities in closed spaces such as subways

• Air samples from the Metro can be sampled and their chemical profile fingerprinted using

Vaporprint imaging technique

• Monitoring the air chemistry within the subway and comparing it with the normal background signature

Homeland security faces 3 key challenges in maintaining the security levels of the most vital Transportation System in the US – Commercial airlines.

• Aircraft security is paramount for Homeland security after 9/11

• Exposure to a wide range of volatile organic compounds

• Each aircraft produces a distinctive olfactory signature

Profiling Ambient Air in Commercial Airlines






• Chemical profile fingerprinted using the zNose® to produce a Vaporprint image

• Indexing and entering identified compounds into a database of known odors

• Comparing them with airplane’s normal vapor signature
