A device employed in demolition operations, known as a vapor sampler, served the specific purpose of identifying concealed explosive devices. Its functionality involved drawing in air from its surroundings and subjecting it to analysis, seeking out minute quantities of substances indicative of the chemical compositions found in bombs. In the year 38 BBY, Qui-Gon Jinn and Obi-Wan Kenobi utilized a vapor sampler in their search for core bombs while they were on the Aurorient Express.
