Title
Preparation of Trace Explosives Standards by Advanced Inkjet Printing
Abstract
Accurately defined test samples of explosive materials on different substrates, precise in amount and sample coverage, are critical for evaluating the performance of existing sensors and predicting the performance of future detection capabilities. Drop-on-demand and inkjet printing technology has become a promising method of producing standardized chemically contaminated test materials with high precision, accuracy, scalability and flexibility to allow for the inexpensive high-throughput production of test materials for the evaluation of stand-off sensors. Since more than ten years Fraunhofer ICT has been using a GeSiM Nano-Plotter NP 2.1 to produce test samples of explosive materials on different substrates in several national and European projects, among them NATO STANDEX, NATO SET-237 and NATO DEXTER. Currently, the work is continued within the NATO Task Group SET-316 “Realistic Trace Explosives Test Standards for Evaluation of Optical Sensors in Relevant Scenarios” and the EU H2020 Project RISEN. The Poster will show examples of printed samples and describe the methods of quality control regarding the accurate mass loading as well as the uniform surface coverage and morphology of the deposits.
