| 20090249897 | TRANSFER OF SUBSTANCES ADHERING TO SURFACES INTO A DETECTION INSTRUMENT - A method for the transfer of target substances (drugs, pollutants, explosives and chemical warfare agents) from a surface to be investigated into a detection instrument, the target substances being present in the form of condensations of vapors on the surface itself or on particles adhering to it, or as particles sticking to the surface. The method comprises the steps of (a) moving a sampler, consisting of either a fiber bundle or a fastener strip with fiber loops, over the surface to be investigated, thus transferring substances to the fibers or the fiber loops or embedding particles into the gaps between the fibers or the fiber loops of the sampler, (b) transferring the sampler into a desorption device of the detection device, and (c) heating the sampler to evaporate the target substances. Various sampler designs can be incorporated into devices using the method. | 10-08-2009 |
