zNose^â Detects Liquid Bomb (TATP) and Its Chemical Components

Monday August 14, 2006, 9:00 am ET

NEWBURY PARK, Calif.--(BUSINESS WIRE)—August 14, 2006-- An innovative homeland security product called zNose^â manufactured by a Southern California high-tech company Electronic Sensor Technology, Inc. (OTCBB:ESNR-News) has a proven capability in detecting a liquid bomb called TATP and its related chemical components in addition to detection of conventional explosives, according to Dr. Teong C. Lim, President and CEO of the company.

The global alert of the terrorists planned attack on international passenger airlines in London that was uncovered yesterday indicated that the bomb ingredients they were using in the planned attacks was tri-cycloacetone peroxide (TATP). This crystalline material can be produced from common acetone, peroxide, and sulfuric acid, yet it has the explosive power of RDX. zNose^â has a long proven record of detecting these ingredients either in a finished TATP chemical form or its component, acetone, with a sensitivity of parts per billion (10^-9) in less than ten (10) seconds. TATP is a relatively volatile explosive and readily produces vapors which can be detected by the zNose. The most publicized account of TATP usage was that of Richard Reid, the shoe bomber, but TATP is often used by Hamas “human” bombers in Israel.
