介绍了一种快速、高效、实时的过氧化氢炸药TATP定量分析方法。该方法利用化学试剂离子与固体TATP上方蒸气的快速离子-分子反应。考察了三种试剂离子（h30o +、O2+、NO+）的反应。虽然这三种离子都与TATP发生了接近碰撞率的反应，但只有NO+的产物离子为TATP基炸药提供了明确的证据。气相中TATP的检出限为10 ppb (4 × 10（-10) mol L(-1)）。
A fast, efficient, real-time method for the quantitative analysis of the peroxide explosive, TATP, is described. The method utilizes rapid ion-molecule reactions of chemical reagent ions with the vapor above solid TATP. The reactions of three reagent ions (H3O+, O2+, NO+) were examined. Although all three ions exhibited a near-collision-rate reaction with TATP, only NO+ showed product ions that provide unequivocal evidence for a TATP-based explosive. The limit of detection of TATP in the gas phase is 10 ppb (4 x 10(-10) mol L(-1)).
