Abstract

The feasibility of the use of piezoelectric drop-on-demand inkjet printing to prepare test materials for trace explosive analysis is demonstrated. RDX (1,3,5-trinitro-1,3,5 triazcyclohexane) was formulated into inkjet printable solutions and jetted onto substrates suitable for calibration of the ion mobility spectrometry (IMS) instruments currently deployed worldwide for contraband screening. Gravimetric analysis, gas chromatography/mass spectrometry (GC/MS), and ultraviolet-visible (UV-vis) absorption spectroscopy were used to verify inkjet printer solution concentrations and the quantity of explosive dispensed onto test materials. Reproducibility of the inkjet printing process for mass deposition of the explosive RDX (1,3,5-trinitro-1,3,5 triazcyclohexane) was determined to be better than 2% for a single day of printing and better than 3% day-to-day.

摘要

证明了使用压电按需滴墨打印技术制备痕量爆炸物分析测试材料的可行性。将 RDX（1,3,5-三硝基-1,3,5-三嗪环已烷）配制成喷墨打印溶液，并喷射到适合目前全球用于违禁品筛查的离子迁移谱（IMS）仪器校准的基底上。通过重量分析、气相色谱/质谱（GC/MS）和紫外可见（UV-vis）吸收光谱法验证了喷墨打印机溶液浓度和喷射到测试材料上的爆炸物的量。对于 RDX（1,3,5-三硝基-1,3,5-三嗪环已烷）的爆炸物的喷墨打印过程的重现性，每天的打印精度优于 2%，每天之间的打印精度优于 3%。
