Pine Brook, NJ, - Smiths Detection, the world’s leading provider of trace detection and x-ray security screening equipment, today announced the first deployment of its Sentinel II explosive detection walk-through trace portal since completing field testing by the Transportation Security Administration (TSA). The Sentinel II, a next-generation passenger security screening technology, will be deployed in Terminal A at Newark Liberty International Airport. Additional New York-area deployments at JFK International Airport and La Guardia International Airport are scheduled for August and September 2005.

During the TSA’s field trials, the Sentinel II was tested in Terminal 1 of JFK International Airport, as well as at multiple international airports throughout the U.S., to determine the systems capabilities and impact on terminal operations.

“Smiths Detection is proud to participate in enhancing passenger safety at three of the country’s busiest airports,” said Mark Laustra, Vice President, Transportation Security Technology & Programs, Smiths Detection. “The Sentinel II adds a key layer to passenger checkpoints and provides an additional level of security to our nation, making air travel more secure.” The Sentinel II will enhance explosive detection capabilities by rapidly detecting various explosive substances that could emanate from a passenger’s clothing, skin or hair. This non-invasive walk-through scanner will help reduce the need for pat down procedures at the checkpoints with the devices.

Using Ion Mobility Spectrometry (IMS), the walk-through trace portal operates automatically, passing air gently over a person from head to toe, releasing any particles that are naturally absorbed by or cling to a person’s clothing or body. These particles are then drawn by a vacuum and collected for analysis at the passenger’s feet. Detection of particles or vapors can indicate that a person is either carrying an explosive device or has come into contact with explosive substances.

Following the Newark Liberty installation, the Sentinel II will be deployed at other airports in the near future including: Washington Reagan Airport, Washington Dulles International Airport, San Juan International Airport, Charlotte International Airport, and Pittsburgh International Airport. During field trials, the system was tested at Baltimore-Washington International Airport, Jacksonville International Airport and McCarran International Airport.
