Abstract

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)).

摘要

本文描述了一种用于定量分析过氧化物炸药三过氧化三丙酮（TATP）的快速、高效、实时方法。该方法利用化学试剂离子与固体TATP上方蒸汽的快速离子-分子反应。研究了三种试剂离子（H3O+、O2+、NO+）的反应。尽管所有三种离子与TATP都表现出近碰撞速率反应，但只有NO+显示出能为基于TATP的炸药提供明确证据的产物离子。气相中TATP的检测限为10 ppb（4×10(-10) mol L(-1)）。
