Explosives trace detection (ETD) characterized by non-contact sampling is a promising technology to enable highthroughput and automatic detection. In this study, we attempted to develop a standard sample and evaluation method for ETD. Soil particulate was coated with trinitrotoluene (TNT) to be used as a standard sample. Adsorption of TNT was confirmed by liquid chromatography-mass spectrometry. The standard sample was filled in the hollow on a metal plate that was used as the test target. The hollow plays a role for maintaining the amount and the position of the sample between measurements. We obtained the sensitivity of ETD using the standard sample and test target. Collection efficiency, a pure performance of the sampling part of the ETD, was also acquired. The standard sample and evaluation method using that sample and the plate with the hollow will be useful for the improvement of ETD with non-contact sampling.
