HAIFA, Israel, Sept. 13 (UPI) -- An Israeli company that makes advanced explosives detectors has named a Turkish distributor, adding to a growing list of customers that includes U.S. soldiers in Iraq and Afghanistan, plus armies, police departments and security organizations in England, Australia and India.

Acro Security Technologies' product is the Peroxide Explosives Tester. Peroxide-based explosives are undetectable by devices that screen for conventional, nitrogen-based explosives like TNT and nitroglycerin.

"That someone will bring down a plane with TATP is not a question of if; it is a question of when," Ehud Keinan, the inventor of PET and Acro's chief scientific consultant, told United Press International in a telephone interview. TATP is triacetone triperoxide, the compound behind some 90 percent of peroxide-based explosives.

Peroxide-based explosives, familiar on the scene at Israeli bus bombings for nearly 30 years, blasted onto the world's radar screen in 2005 when they were used in the July 7 bombing in London, Keinan said.

"The explosions were caused by homemade organic peroxide-based devices, a substance which is dangerous to manufacture but does not require a great deal of expertise," according to a BBC summary of the findings in the British government's "7 July Report" on the attacks.
