We describe the proof of concept of a portable testing setup for the detection of triacetone triperoxide (TATP), a common component in improvised explosive devices. The system allows for field testing and generation of real-time results to test for TATP vapor traces in air by simply using circulation of the air samples through the sensing mechanism under the air conditioning system of an ordinary room. In this way, the controlled trapping of the analyte in the chemical sensor gives reliable results at extremely low concentrations of TATP in air under real-life conditions, suitable for daily use in luggage storage for airlines or a locker room for a major sporting event. The reported fluorescent methodology is very sensitive and selective, allowing for the trapping of triacetone triperoxide in the chemical sensor to give reliable results at very low concentrations in air under ambient conditions, by comparing the fluorescence of the material before and after exposition to TATP traces in air.
我们描述了一种便携式测试设备的概念验证，该设备用于检测三过氧化三丙酮（TATP），这是简易爆炸装置中的常见成分。该系统允许进行现场测试，并实时生成结果，通过简单地将空气样本循环通过传感机制，在普通房间的空调系统下测试空气中 TATP 蒸气痕迹。通过这种方式，在实际生活条件下，通过控制化学传感器中分析物的捕获，可以在空气中 TATP 极低浓度下获得可靠的结果，非常适合航空公司行李存储或大型体育赛事更衣室的日常使用。所报道的荧光方法非常灵敏和选择性强，通过比较暴露于空气中 TATP 痕迹前后材料的荧光，可以在环境条件下空气中非常低的浓度下，通过化学传感器捕获三过氧化三丙酮，从而获得可靠的结果。
