摘要:

为及时有效地查出行李、包裹和人身中隐藏的爆炸物,利用荧光淬灭(FQ)和离子迁移谱(IMS)2种痕量爆炸物检测仪器,分别通过擦拭和吸气2种采样方式,检测三硝基甲苯(TNT)、黑索金(RDX)、三过氧化三丙酮(TATP)、硝酸铵(AN)等多种爆炸物,并主要从报警时间和恢复时间2个方面进行对比分析。结果表明:擦拭采样情况下,FQ的平均报警时间比IMS少约2 s,平均恢复时间比IMS少约30 s,具有更高的检测效率。吸气采样情况下,FQ仪器可检测TNT和TATP,IMS仪器难以检测爆炸物。

Abstract:

In order to timely and effectively detect the explosives hidden in luggage, packages and individuals, multiple explosives such as trinitrotoluene(TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine(RDX), triacetone triperoxide(TATP), ammonium nitrate(AN), etc. were detected by FQ and IMS instruments by wiping and aspiration sampling methods. The comparison was mainly made from two aspects: alarm time and recovery time. The experimental results show that under wiping sampling, the average alarm time of FQ is about 2 seconds less than that of IMS, and the average recovery time is about 30 seconds less than that of IMS, which has higher detection efficiency. In the case of aspirated sampling, FQ instruments can detect TNT and TATP, while it is difficult for IMS instruments to detect explosives.

Key words: fluorescence quenching (FQ), ion mobility spectrometry (IMS), trace, explosive detection, alarm time, recovery time
