摘要: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.
