Abstract
An method of, and an apparatus for, collecting a sample of a substance of interest, utilizes an apparatus having a device for collecting a vapor sample and a device for retaining a substrate. A substrate, having a working portion and a mounting portion, is mounted by the mounting portion of the substrate, whereby the working portion of the substrate is exposed for use. The apparatus so that the working portion of the substrate traverses surfaces of interest, to collect a particulate sample. A device for sampling vapor is operated to obtain a vapor sample. The vapor and particulate samples collected are analyzed.
