Triacetone triperoxide (C(9)H(18)O(6), molecular mass of 222.24 g/mol) (TATP) is a powerful explosive that is easy to synthesize using commonly available household chemicals, acetone, and hydrogen peroxide 1 2. Because of the simplicity of its synthesis, TATP is often the explosive of choice for terrorists, including suicide bombers. For providing safety to the population, early detection of TATP and isolation of such individuals are essential. We report unambiguous, high-sensitivity detection of TATP and its precursor, acetone, using room-temperature quantum cascade laser photoacoustic spectroscopy (QCL-PAS). The available sensitivity is such that TATP, carried on a person (at a nominal body temperature of 37 degrees C), should be detectable at some distance. The combination of demonstrated detection of TATP and acetone should be ideal for screening at airports and other public places for providing increased public safety.
三丙酮三过氧化物（C₉H₁₈O₆，分子量222.24克/摩尔）（TATP）是一种烈性炸药，使用常见的家用化学品丙酮和过氧化氢很容易合成。由于其合成方法简单，TATP经常是包括自杀式炸弹袭击者在内的恐怖分子的首选炸药。为了保障民众安全，早期检测TATP并隔离相关人员至关重要。我们报告了利用室温量子级联激光光声光谱法（QCL-PAS）对TATP及其前体丙酮进行明确、高灵敏度的检测。现有的灵敏度使得携带在人身上（在37摄氏度的正常体温下）的TATP在一定距离外应该能够被检测到。已证实的对TATP和丙酮的检测相结合，对于在机场和其他公共场所进行安检以提高公共安全来说应该是理想的。
