摘要：
The present invention provides a skin surface sampling device in which a supply tube and a recovery tube are housed in an elongated hand-holdable tubular sleeve, the sleeve having upper and lower ends positioned along a longitudinal axis and the lower end being provided with a sampling head in which: the supply tube is adapted to convey liquid from a liquid source to the sampling head the recovery tube is adapted to convey liquid from the sampling head to a liquid collection vessel the sampling head has a planar surface adapted for application to the surface of the skin to form a contact therewith during sampling the planar surface has a liquid entry port adapted for liquid communication with the supply tube and a liquid exit port adapted for liquid communication with the recovery tube and characterized in that: the liquid entry port and the liquid exit port are connected via a guide channel which is adapted to guide liquid from the liquid entry port, along the surface of the skin for the elution of materials on the skin surface, and then to the liquid exit port for recovery. The device can be used in a rapid and non-invasive system of skin surface sampling, enabling the sampling of a wide range of compounds (including but not limited to VOCs and SVOCs) from the surface of the skin, and which can be used over all areas of the body.
