Title: Application of Inkjet Printing Technology to Produce Test Materials of 1,3,5-Trinitro-1,3,5 Triazcyclohexane for Trace Explosive Analysis
Published: October 15, 2010
Abstract: The feasibility of using piezoelectric drop-on-demand inkjet printing to prepare test materials for trace explosive analysis is demonstrated. Both pure high explosives and plastic-bonded putty explosives were 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 spectroscopy (UV-Vis) were used to verify inkjet printer solution concentrations and the quantity of explosive dispensed onto test materials. Reproducibility of the inkjet printing process for 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.
