Abstract

The paper presents the results of the theoretical and practical research on the detection and examination of the threat traces taken from samples of explosive substances from experimental attempts on explosive materials in various working environments. The use of I-SCAN LSD high-performance specialized equipment that has been purchased within the project, has enabled the detection and examination of small amounts of low volatility organic substances on the basis of ion mobility spectrometry as a result of explosive testing at different locations at the level of the industrial site within the INSEMEX Polygon and quantifying the degree of contamination of contaminated objects.

Highlights

Detecting and identifying explosives are important stages of judicial or intervention action to prevent and combat both crime and the implementation of terrorist threats, a violent and destructive plague of contemporary society
The results of experimental research on explosive materials detonated in different working environments from the point of view of the threat traceability from analysed explosives samples or from controlled explosions conducted in the INSEMEX Polygon, highlight the presence of explosive substances detected and examined using the I-SCAN LSD specialized equipment, confirming the qualitative accuracy of the result indicators in full agreement with the nature and chemical composition of the explosive products tested according to the configuration and specificity of the test environment
Analysis of samples for the traces detection of explosive materials and identification of the material for technical or criminal investigations are complex, laborious and difficult activities to be achieved. They require, on the one hand, rigorous and precise investigations based on the assurance of the quality of the harvested samples, with the perception of forensic tactics and procedural actions, and on the other hand the endowment with highperformance analysis equipment and apparatus that offers the possibility to obtain real results in the shortest time

Summary

Introduction

Detecting and identifying explosives are important stages of judicial or intervention action to prevent and combat both crime and the implementation of terrorist threats, a violent and destructive plague of contemporary society. The I-SCAN LSD specialized equipment (figure 2) applies the principles of the tested and reliable method of ion mobility spectrometry This process is based on the separation of ions from substances, depending on mobility, while moving them into the constant electric field drift tube. Identification of explosive substances based on the rapid detection and examination of specific characteristics was carried out on the basis of the PL-01/2017 working procedure, using the I-SCAN LSD performance equipment, designed to detect low amounts of organic substances with low volatility on the basis of ion mobility spectrometry >4-5@.
