Secure areas, such as at airports or other security-critical facilities, are entered from freely accessible areas, often by means of access locks. This bottleneck, which is present in any case, is used to check for substances of concern, such as drugs or explosive materials. In the case of solids, as is known, particles extracted from the access lock and retained in a screen are vaporized and the vapor is examined. Several of the screens are arranged on rotatable carrying disks and undergo consecutively the steps of vaporization and analysis. The aim of the invention is to make known methods more efficient in order to increase the throughput through such access locks. The aim is achieved by a device for which available heating and extraction elements are assigned to multiple rotational positions of the carrying disks, whereby adjacent rotational positions lie apart from each other by only half the distance of two screens.
