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.
