TATP, the explosive used by terrorists in the Brussels bombing, the Paris attack in 2015, London bombings in 2005 and 2006, and by the "shoe bomber" in 2001, is now detectable with the XCAT Explosives, Narcotics, and GSR Detection System. Fielded since March 2013, the XCAT can now detect TATP and HMTD in addition to Nitrates, Nitramines, and Nitroaromatics.
The XCAT utilizes simple swipes to obtain a sample and provides users a red light/green light result. The addition of the PER-700 sampling card is an enormous step up in capability for the XCAT, giving users complete threat detection. The XCAT is ideal for portable screening operations and intelligence gathering.
